Phasecraft Algorithm Suite Simulates Materials on Near-Term Quantum Computers

Informative summary

  • Phasecraft produces a set of algorithms that make materials simulation on quantum computers simpler and more efficient than ever.
  • His work was published in the scientific journal Nature.
  • The method showed that a material used in lithium-ion battery technology could be simulated with 410,000 quantum gates, up from 1.5 trillion previously.

PRESS RELEASE – Phasecraft, the startup led by leading academics developing world-leading quantum algorithms, has developed another unprecedented set of algorithms that makes materials simulation on quantum computers simpler and more efficient than ever.

Understanding how materials behave is one of the most promising applications of quantum computers, from pioneering new cathodes for batteries to creating next-generation solar cells. However, short-term quantum computers cannot perform complex simulations because they are limited by the number of operations they can reliably perform and have a limited number of qubits.

Phasecraft’s proprietary approach eliminates these limitations by bringing together classical material mapping methods with novel quantum techniques to simulate their behavior. The first stage performs calculations and optimizations on classical computers to produce an effective representation of the material, while the second produces the world’s most efficient quantum circuits to simulate the behavior of that material. The entire framework is encapsulated in an integrated software pipeline that runs from the description of a material to a quantum circuit to simulate that material.

This approach, described in the Nature Communications paper Towards Near-Term Quantum Simulation of Materials, dramatically reduces the number of quantum gates needed to run the simulations, by a factor of more than a million in some cases.

To put this into perspective, Phasecraft’s approach was able to demonstrate that lithium copper oxide (Li2CuO2, a material used in advanced lithium-ion battery technology), could be simulated with 410,000 quantum gates. The previous reference technique used 1.5 billion. What’s more, Phasecraft’s approach not only shows how the simulation process can be simplified, but can also identify which materials are best suited for quantum simulation in the first place.

Real world impact

This breakthrough, which was partly funded through grants from Innovate UK and the National Quantum Computing Center (NQCC) and carried out in collaboration with the Department of Scientific Computing at the Science and Technology Facilities Council (STFC), is a substantial step towards the ability to run complex systems. simulations of materials on short-term quantum computers, enabling simulations that were previously out of reach. It is also a further advancement in Phasecraft’s mission to close the gap between the promise of quantum technology and the real-world applications of the technology.

Phasecraft’s breakthrough could accelerate advances in the development of more efficient batteries, photovoltaics, supercapacitors and fuel cells, which are crucial to the advancement of renewable energy technologies. Additionally, more accurate simulations using quantum computers could lead to a better understanding of how drugs interact at the molecular level, accelerating the development of new drugs and reducing cost and time to market.

Modeling database

Coinciding with the publication of its latest paper, Phasecraft launched its materials modeling quantum complexity database. This database reveals the complexity of the quantum circuitry of more than 40 materials identified with potential for practical applications.

In particular, it highlights the depth of each material’s quantum circuitry using the approach described in the recent Phasecraft paper. Each material lists the depth of the current circuit and the number of qubits needed, along with the main structural properties of the material. Researchers can filter the materials database by application, from batteries to construction, nuclear energy, electronics and more.

Toby Cubitt, co-founder and CTO and chief scientific officer at Phasecraft, said: “The improvements we have made to circuit depth with our latest algorithms fundamentally change the landscape and timeline of materials simulation in quantum computers. What was once considered out of reach for near-term quantum computers now appears to be within reach. “We have taken an important step toward the promise of modeling and designing novel materials using quantum computing.”

Ashley Montanaro, co-founder and CEO of Phasecraft, said: “By publishing our materials database, we aim to bridge the gap between the theory of quantum computing and its practical application. With each material’s circuit depth and qubit requirements at their fingertips, scientists and engineers now have a new tool to assess where the greatest benefits of quantum computing lie in the quest for accurate materials modeling. “It is the culmination of several years of research and a testament to the progress we have made in bringing materials modeling on quantum computers closer to reality.”

Gilberto Teobaldi, theoretical and computational physics group leader in the Department of Scientific Computing at the UK Science and Technology Facilities Council, said: “We were delighted to collaborate with Phasecraft on their materials modeling database. The research carried out on this database, as well as the database itself, represents a significant step in the application of quantum computing to materials science, showcasing Phasecraft and the UK’s commitment to pioneering the quantum frontier. ”.

Michael Cuthbert, director of the National Center for Quantum Computing, said: “When we launched the NQCC three years ago, it was with the intention of helping researchers and organizations access tangible benefits from quantum computing. Phasecraft’s work on materials modeling, including the publication of its database, is exactly the type of important project we are excited to support and champion. “Innovative companies like Phasecraft are part of our mission to make the UK a world leader in quantum computing.”
