By experimenting with designing quantum algorithms, QuAIL hopes to use quantum computers to tackle calculations that otherwise would be impossible. Today, the Quantum Artificial Intelligence Laboratory (QuAIL), is where NASA conducts research to determine the capabilities of quantum computers and their potential to support the agency’s goals in the decades to come. Located at Ames, the lab conducts research on quantum applications and algorithms, develops tools for quantum computing, and investigates the fundamental physics behind quantum computing. But enterprises need to realize that it’s early days for gate model quantum computing, and that gate model systems may never be better than annealing systems in solving optimization problems. Unlike annealing quantum computers, gate model quantum computers require error correction—the biggest single engineering challenge for quantum computing. If that state collapses, a quantum system should be able to correct the error and roll back to where it left off.
Whatever the design, the clever stuff happens when qubits are carefully coaxed into ‘superposition’ states of indefinite character — essentially a mix of digital ones and zeroes, rather than definitely being one or the other. Running algorithms on a quantum computer involves directing the evolution of these superposition states. The quantum rules of this evolution allow the qubits to interact to perform computations that are, in practical terms, impossible using classical computers. The problem is compounded by the difficulty of building the hardware itself. Quantum computers store data in quantum binary digits called quantum bits, or qubits, that can be made using various technologies, including superconducting rings; optical traps; and photons of light. Some technologies require cooling to near absolute zero, others operate at room temperature.

Rather than quantum internet, most experts prefer the term quantum networks. While quantum computers perform calculations on quantum information, quantum networks transport quantum information. If we can successfully exchange data between quantum computers, while maintaining the quantum state, we can run quantum calculations in parallel, further improving computation speeds.
Quantum Computing leverages the principles of quantum mechanics, enabling the computational power to solve specific problems currently intractable for classical computers (e.g., cracking cryptographic keys). Since we are getting to a point where we can no longer build smaller, more powerful, more efficient devices with conventional methodologies, we need to think of new ways for technological progress. The manufacturing of microchips is reaching its limits in the use of traditional architectures. Hence, new and more advanced technologies need to address the challenges of increasing energy consumption and data processing. Looking ahead to the next generation, computing will comprise technologies that enable high-performance applications far beyond today’s possibilities.

The next logical step was to build devices that work with light and matter to do those calculations for us automatically. The complexity of these control systems is aligned to our expertise, because we’ve been building them for decades. As a leader in hardware, software and intuitive user interfaces, we have the end-to-end capabilities necessary to design, build, and integrate critical subsystems and components to facilitate trapped-ion technology. That’s why we’ve spent more than a decade focused on ways to not only help architect this massive expansion of computational power and problem solving, but accelerate it, too. Honeywell Quantum Solutions and Cambridge Quantum have combined to form Quantinuum – the world’s largest integrated quantum computing company. On August 9 this year, US President Joe Biden signed an executive order to restrict US firms and funds from investing in China’s semiconductor, quantum computing and artificial intelligence sectors.
With a sufficiently powerful quantum computer, Shor’s algorithm can be used to decode public-key cryptography, which uses very large primes deemed computationally intractable by classical computers. Without an understanding of the nature of electromagnetism and the structure of atoms, we wouldn’t have electricity and the integrated circuitry that power computers. It was only a matter of time, then, before we thought of exploiting the most accurate, fundamental description of physical reality provided by quantum mechanics for computation.
Science X Account
Quantinuum has already proven its value in the fields of cybersecurity, computational chemistry, compositional intelligence, machine learning, optimization and simulation. In 1994, mathematician Peter Shor introduced a quantum-computing algorithm that could reduce the time it takes to find the prime factors of large numbers from billions of years using a conventional transistor-based computer to a few days using a quantum computer. This was an enormous breakthrough, because prime factorization is the foundation for much of our present encryption and information security infrastructure. Seven years later, IBM scientists successfully demonstrated the algorithm on a quantum machine—albeit a very small one—for the first time, proving that quantum computers could be built and that Shor’s algorithm could be implemented.
You may be surprised to learn that our enterprise customers have already built hundreds of quantum applications across many industries. Blockchain is a record-keeping technology designed to make it impossible to hack the system or forge the data stored on it, thereby making it secure and immutable. Development of quantum theory began in 1900 with a presentation by German physicist Max Planck to the German Physical Society.
Quantum theory explains the behavior of energy and material on the atomic and subatomic levels. There are three ways to access IBM Quantum systems and services, scaled to meet the needs of all kinds of users. Quantum entanglement is an effect that correlates the behavior of two separate things. Physicists have found that when two qubits are entangled, changes to one qubit directly impact the other. An IBM Quantum processor is a wafer not much bigger than the one found in a laptop.

(c) The United States should ensure the protection of U.S.‑developed quantum technologies from theft by our adversaries. This will require campaigns to educate industry, academia, and SLTT partners on the threat of IP theft and on the importance of strong compliance, insider threat detection, and cybersecurity programs for quantum technologies. As appropriate, Federal law enforcement agencies and other relevant agencies should investigate and prosecute actors who engage in the theft of quantum trade secrets or who violate United States export control laws. To support efforts to safeguard sensitive information, Federal law enforcement agencies should exchange relevant threat information with agencies responsible for developing and promoting quantum technologies.
Healthcare and life sciences
Quantum sensing, which can measure changes in electrical and magnetic fields, has major implications for military technologies such as autonomous weapons, stealth, and radar. Perhaps unsurprisingly, quantum computers are incredibly complex machines that are difficult to bend to one’s will. Quantum processors consist of chips that are similar in size to those used in laptops and smartphones, but they need to operate at incredibly low temperatures—close to absolute zero, or minus 460 degrees Fahrenheit—to work. That is generally achieved by pumping supercooled fluids such as helium into the chamber that houses the chip.
Specifically, scientists search for a speedup to solve intractable problems that take on exponential complexity. So, in addition to simulating complicated quantum mechanical systems, the applications of quantum computing extend to industrial problems like optimizing combinatorial systems in a factory or simulating financial systems by making analogies to physical ones. For example, some modern research compares financial portfolio risk to energy levels, which can be optimized using quantum computation. In particular, building computers with large numbers of qubits may be futile if those qubits are not connected well enough and cannot maintain sufficiently high degree of entanglement for long time. Therefore, it is desirable to prove lower bounds on the complexity of best possible non-quantum algorithms (which may be unknown) and show that some quantum algorithms asymptomatically improve upon those bounds.

Considering that most problems would require hybrid solutions using a mix of classical and quantum, strong capabilities in classical technologies would be equally critical to success. The QC ecosystem comprises capabilities offered by providers, at various technology layers (hardware, systems software, cloud, tools, acceleraors, solutions, and more).
