Regardless of your industry (finance, pharmaceutical, logistics, security, etc.), map out potential use cases and monitor results regularly.
#Complete Guide: Success & Powerful Best AI Tools for Business in USA
Some of the largest global challenges (e.g., developing a new medicine, designing new materials to combat climate change) are akin to solving mazes that have trillions of incorrect paths. Even the fastest computers currently available will become lost and will be forced to examine every path individually at an exponential rate (i.e., much longer than the age of the universe). These limitations are inherent to the design of current computing systems.
What if a new type of computer could evaluate all possible paths simultaneously? The promise of quantum computing is to revolutionize this capability by enabling the evaluation of complex, maze-like problems. Quantum Computing is not about enhancing your video games, but about developing a new class of computers that are capable of addressing previously unsolvable, maze-like problems. Given the vast potential of quantum computing, there is fierce competition to shape its future in America.
Quantum Computing has many significant impacts on society (e.g., enabling the development of hyper-efficient batteries, improving the accuracy of medical research modeling). Therefore, the overall impact is tremendous. Ultimately, the impact of quantum computing could transform several major industries (e.g., financial modeling may enable unprecedented levels of accuracy).
There are several pioneers shaping the future of quantum computing, ranging from well-established technology giants to bold startups. Each of these innovators is racing to make science fiction a reality by developing their own approaches to harnessing the power of the quantum realm.
Summary
IBM is building a wide-open architecture for broad-access to quantum computing; this includes a quantum cloud platform where researchers and businesses can experiment and build their skills now. Google has demonstrated high-profile advances, including “quantum advantage,” showing that quantum-based systems can perform certain types of calculations faster than classical systems.
Other companies, besides large tech firms, are advancing quantum computing through alternative architectures. For example, IonQ is using trapped atoms controlled by lasers to develop more stable qubits, while Rigetti is focused on creating hybrid quantum/classical systems that will enable near-term practical applications of quantum computing.
Currently, because the technology is still in its early stages, most companies have few ways to generate revenue from quantum computing other than through “Quantum Computing as a Service” (QCaaS) models, partnerships, and grants. In addition, the U.S. federal government is heavily investing in the National Quantum Initiative, viewing quantum-based systems as important for both U.S. economic competitiveness and national security.
The article concludes that the impact of quantum computing will most likely come quietly, through improved medicine, materials, and systems, before we begin to notice its presence in our daily lives. This approach is consistent with how other emerging technologies have developed.
What Makes a Quantum Computer So Different? The ‘Spinning Coin’ Secret
A laptop or phone operates under a simple yet incredibly powerful principle; The brain of the laptop/phone is comprised of billions of switches referred to as bits that exist in one of two possible states, on (1) or off (0). For the vast majority of computing applications, this binary system is perfect and sufficient; however, when dealing with humanity’s largest issues, it is like searching for the shortest path through a massive maze using the methodical process of testing one possible route at a time.
On the other hand, Quantum Computers utilize a vastly different paradigm than their classical counterparts. A fundamental building block of a Quantum Computer is known as a Qubit. In many ways, a Qubit can be thought of as a spinning coin. While it is airborne, it cannot be considered to be either Heads or Tails until it comes to rest, and while it is airborne, it exists as a combination of both possibilities simultaneously.
The strange yet powerful phenomenon of existing in multiple states simultaneously is known as Superposition, and it is a true characteristic of Quantum Physics. Therefore, because a single Qubit is capable of representing the values of 1, 0, and everything in between simultaneously, a Quantum Computer does not need to examine each possibility individually and sequentially. Rather, it can evaluate a vast number of possible solutions simultaneously and arrive at the correct solution exponentially faster.
Of course, creating and controlling these ‘spinning coins’ is, while an impressive technological achievement, still a formidable task. Researchers around the world are actively pursuing various alternatives to achieve this goal; the central issue remains the same: How do we maintain the Qubit in its powerful Superposition State long enough to perform the necessary calculations? As researchers struggle to solve this problem, they are engaged in an international high-stakes competition. Two major players in this competition are Google and IBM.

Meet the Titans: How IBM and Google Are Leading the Quantum Race
IBM and Google are at the forefront of this exciting race to create functional quantum computers. Each company is investing massive amounts of money (billions) to build a working quantum computer. However, each is approaching the problem from vastly different directions. One might consider IBM’s approach to creating an open public highway system, while Google is competing to build the world’s fastest car.
IBM took an open approach to creating a highway system and making a quantum computer available to anyone who wants to use one. In late 2016, IBM became the first company to offer a publicly accessible cloud-based quantum computing service called IBM Quantum Experience.
The Quantum Experience is analogous to a video streaming service. Just as you do not need to purchase expensive equipment in order to view a high-definition movie via streaming, IBM’s customers do not need to purchase or maintain a large, powerful quantum computer in order to run a quantum algorithm. Rather, customers can run their algorithms directly on IBM’s Quantum Experience hardware remotely, using nothing more than a laptop running standard software. IBM’s strategy is to create a growing community of users who will help identify practical applications of quantum computers today.
Google has adopted an entirely different strategy to demonstrate the raw power of quantum computers. Google has been attempting to create the ultimate “supercar.” In October 2019, Google announced that it had achieved Quantum Advantage, a milestone marking the point at which a quantum computer can perform a particular type of computation that would be virtually impossible for even the most advanced classical supercomputers.
Although the actual application of the advantage was somewhat abstract, the announcement represented a “Sputnik moment” for the development of quantum computers, demonstrating to the world that quantum computers could indeed outperform the best classical computers.
The approaches employed by IBM and Google to develop quantum computers differ significantly. IBM is developing a broad platform that provides access to quantum computers to as many people as possible, while Google is pursuing a series of individual, record-setting demonstrations of quantum computer capabilities. Despite these differences, both companies are advancing the field of quantum computing.
The massive investments being made by both companies, along with the publicity generated by their competitive efforts, are driving rapid advances in quantum computing. A new class of smaller, more agile startups is also emerging, and some of them are proposing alternative ways of solving problems using quantum computers.
Beyond the Giants: How Startups Like IonQ and Rigetti Are Changing the Game
Even though the titans get all the attention, there is still a lot of exciting development going on in specialized quantum computing start-ups in the U.S. Rather than trying to build the same type of quantum computer, these companies are proposing new designs and architectures. It is important to have several approaches, since no one yet knows which architecture will ultimately be better.
If you think back to the early days of automobile manufacturing, many engineers were working on developing both electric motors (the battery) and perfecting the gasoline engine (the internal combustion engine). In today’s quantum computing world, we are seeing the same thing. Both Google and IBM are using very small, extremely cold electrical circuits (super-cooled) as their qubits. However, other companies are developing an entirely different type of qubit altogether.
IonQ is one of the companies at the forefront of this new approach. They are the first pure-play quantum computing company to go public. Their approach is to utilize individual atoms, laser-suspended in mid-air, as their qubits. As such, they believe that their “nature-made” qubit will provide a much more stable and accurate quantum processor, enabling a different “engine” design for their computers.
Rigetti Computing is another leader in this space. Like the large companies mentioned above, Rigetti also utilizes superconducting technology for its qubits. However, unlike larger companies, their goal is to develop systems in which their quantum chips work in tandem with the best classical supercomputers. They call this a hybrid system. By doing so, they hope to find solutions to real-world problems much faster by leveraging the strengths of each processor type. Rather than competing against each other, these start-ups are expanding our definition of what a quantum computer can be.

How Do Quantum Companies Make Money on a Technology That’s Still Being Built?
What is the $1B Question? If quantum computers are currently not producing new wonder-drugs, how can Quantum Companies make money now? Unlike traditional products, these companies are selling the ability to use, rather than the final product. Essentially, every leading quantum computing company operates under what is known as “Quantum Computing as a Service” (QCaaS).
Think of this as a time-share for a super-intelligent brain. Rather than purchasing one of these huge, fragile, and expensive machines, a company can simply rent time on it via the Cloud. From there, researchers and developers at other companies can run experiments and test their algorithms on their laptops, gaining hands-on experience with this futuristic technology without spending tens of millions of dollars to purchase an entire machine.
Who are the first customers? These are primarily large corporations in financial services, automotive, and pharmaceuticals, as well as major university research labs. While the initial intention is not to produce profits immediately, these organizations are strategically investing in training their internal teams to be among the first to find a breakthrough when the hardware has sufficient power to support that discovery.
The companies also generate revenue through direct partnerships with each organization on specific research projects and by securing government grants. Government grants are critical, as governments view quantum capability as both an economic development opportunity and a means of establishing a nation’s position in security and global economic competitiveness.
Why Is the US Government Investing Billions? The National Quantum Initiative Explained
Since its emergence as a national strategic priority, quantum computing has been treated by many as significant as the space race or the development of the Internet. Therefore, this is not simply about corporate competition; rather, it’s now a national priority. As a result, the U.S. Government created the National Quantum Initiative (NQI) — a multi-billion-dollar strategic plan to further the advancement of quantum computing in the United States. This is a collaborative effort to integrate the best and brightest minds from government laboratories, universities, and private quantum research organizations so that the nation can be at the forefront of this emerging technological revolution.
There is an extremely high cost to achieving leadership in quantum, with implications that go far beyond who can claim “first.” The nation that develops the first powerful, fault-tolerant quantum computer will have a substantial economic advantage in areas such as drug discovery, materials science, and advanced artificial intelligence. Additionally, there is a strong national security aspect to the potential development of a future quantum computer.
While a quantum computer may never actually exist capable of breaking the encryption that protects virtually all of the world’s digital information, including bank accounts and state secrets, the possibility remains that a future quantum computer could break those codes. For this reason, the pursuit of leadership in quantum is as much a defense imperative as a commercial opportunity.
To achieve the goal of developing a powerful, fault-tolerant quantum computer through the National Quantum Initiative, the initiative is investing in the creation of large-scale research facilities, in the training of a quantum-ready workforce, and in providing necessary grants to companies to create the bridge that must exist between the conceptualization of a new idea and the development of a working prototype.
The massive public investment in this area clearly communicates to all interested parties that quantum computing is no longer simply a distant theoretical concept in academia. Rather, it is viewed as one of the fundamental technologies that will shape the next hundred years, and the competition to develop it is already underway.
What Could We Actually Do With a Quantum Computer? From New Medicines to Better Batteries
Quantum Computing Can Solve Problems That Are Impossible Today
As we mentioned above, the big money being poured into this new technology isn’t because they need better computing power; it is because there are some big challenges that cannot be solved with better computing power. Quantum computing can provide answers to problems involving too many variables to be solved with today’s computing technology.
One example of such an application is medicine. When researchers develop a new drug, the process is very similar to finding a key that fits a lock. The lock is the disease, and the key is the medication. A supercomputer would attempt to find a key by testing billions of key combinations. A quantum computer would examine all possible key combinations simultaneously and determine which combination works best, enabling faster discovery of life-saving medications.
The same capabilities will also allow for the development of new materials. For instance, imagine if researchers could develop a material that doubled the efficiency of solar panels or enabled batteries to charge in seconds. These would be examples of optimization problems, the type of problem that quantum computing can help solve, similar to financial markets, where companies could use the same type of machine to analyze multiple factors in investment portfolios and make them safer and more profitable.
These types of applications may take a long time to develop, but the basic model for how companies will do business is already evolving, raising sustainability concerns for these companies while the technology is still in its infancy.
When Will Quantum Computing Change Your Life? A Realistic Look at the Road Ahead
Quantum computing will likely be years away before we see a laptop that uses it to speed up our daily tasks. The first way you will experience the impact of quantum computing, however, will likely be “behind the scenes,” and you may never realize how much it has changed your life. For example, a cure for a disease could be developed more quickly with quantum computers. New materials that extend battery life beyond current models could also be developed. A new financial system using advanced algorithms to make better decisions based on risk analysis could be developed.
The race to develop practical applications for quantum computing is a marathon (not a sprint), and each of the companies listed here (from large corporations such as IBM and Google to smaller companies focused on innovation, such as IonQ and Rigetti) is developing solutions to previously considered unsolvable problems. Each achievement (i.e., breaking a record for the number of qubits or successfully testing an algorithm) is an important piece of the puzzle in a long and difficult race to develop a quantum computer.
The ultimate goal of quantum computing is to expand the toolbox of human ingenuity. The continuing efforts of the pioneers in quantum computing are bringing the theoretical aspects of quantum theory into practical applications, developing the underlying “invisible” engine(s) that will drive the next generation of discoveries.
Conclusion
The United States is moving beyond its interest in the fascinating physics of quantum computing to a serious, high-risk endeavor to create machines capable of solving problems that classical computers cannot even begin to solve. By leveraging qubits and superposition, quantum systems have the potential to enable entirely new methods for searching vast solution spaces, simulating complex molecular structures, and optimizing processes across industries such as health care, energy, and financial services.
This guide provides examples of how progress toward this goal is being generated by both scale and specialization. For example, IBM’s open-source, cloud-based strategy has contributed to an expanding developer base and has allowed users to experiment with practical applications at an accelerated pace. Simultaneously, Google continues to achieve major scientific milestones that demonstrate what can be achieved with quantum computing at the extreme limits.
n addition to these efforts, startup firms such as IonQ and Rigetti are contributing to the growth of the quantum computing market by providing alternative hardware approaches and hybrid strategies to support near-term solutions.
In addition to the technical contributions described above, the business and policy environment supporting this industry is also beginning to take form. Today, most revenue in the industry is derived from cloud-based subscriptions, partner-based arrangements, and public-private research collaborations funded by significant federal investment through the National Quantum Initiative. It will be a long-term journey before we see the full impact of this investment; however, it is increasingly evident that these organizations are laying the foundation for future technological, scientific, and competitive advantages.
