Phasecraft and NVIDIA report 15x speedup in quantum simulations. Insider Brief * Phasecraft and NVIDIA are combining hardware-adaptive quantum algorithms with NVIDIA accelerated computing to develop applications for fault-tolerant quantum computing. * Under the Wellcome Leap Q4Bio program, the companies generated more than 3,000 VQE molecular emulations across 13 molecular systems and achieved a reported 15x simulation speedup over prior results. * The work used NVIDIA Hopper hardware and cuQuantum to run VQE simulations across 4-to-32 qubit systems, producing data intended to support quantum-enhanced molecular modeling and drug discovery research. PRESS RELEASE - Phasecraft, the world's leading quantum algorithms company, today announced that the company is bringing together Phasecraft's hardware-adaptive ultra-efficient quantum algorithms with NVIDIA AI infrastructure to accelerate the path to fault-tolerant quantum computing. In promising results from an initial collaboration under the Wellcome Leap Q4Bio programme, the companies generated the largest-known Variational Quantum Eigensolver (VQE) emulated molecular database, consisting of over 3,000 unique emulations across 13 molecular systems. This data-set provides a training foundation for quantum-enhanced molecular modeling, which could accelerate drug discovery at a scale previously out of reach, as quantum hardware develops. Simultaneously, a 15x simulation speedup was achieved over prior results when modeling physical, many-body systems integral to biology and health applications. "To make good on the promise of quantum computing, we need to push the limits of today's most capable hardware, both conventional and quantum," said Ashley Montanaro, Co-Founder and CEO of Phasecraft. "We're thrilled to work with NVIDIA and excited by the impressive hybrid computing results produced to date. As quantum computing hardware continues to improve, these kinds of partnerships enable the industry to drive towards quantum applications in health and life sciences and beyond that will meaningfully improve people's lives." "Developing new and more efficient applications is one of the most effective ways to shorten the timeline and expand the possibilities for useful quantum computing," said Sam Stanwyck, Director of quantum product at NVIDIA. "This work with Phasecraft shows the huge advances that can be made when the world's leading researchers have access to state-of-the-art accelerated computing." Wellcome Leap Q4Bio Programme. The companies collaborated as part of the Wellcome Leap Quantum for Bio (Q4Bio) Programme, which sought to answer the question, "What if we could develop new algorithms that deliver quantum advantage for health?" As part of the project, NVIDIA Hopper Architecture was hosted at the University of Nottingham, on which Phasecraft ran large-scale VQE emulations - a hybrid classical-quantum algorithm used to find the ground state of a physical system or molecule. Phasecraft utilized the NVIDIA cuQuantum software developer kit to pair these VQE emulations with training from Phasecraft's proprietary quantum-enhanced Density Functional Theory (DFT) functionals, the computational modeling method used to calculate the electronic structure of many-body systems like molecules, atoms, and condensed matter. By deploying cuQuantum to scale the simulations across the 4-to-32 qubit range, with the vast majority in the 24-28 qubit regime the combined framework achieved a landmark 15x performance leap over prior results when modeling physical, many-body systems. The resulting dataset directly enables more accurate DFT functional training, significantly improving the precision of molecular simulations and providing a scalable path to real-world impact in drug design.

Phasecraft tapped by ARPA-E to develop and apply quantum algorithms for catalyst discovery. June 16, 2026, 11:00 GMT Project aims to reduce reliance on iridium and other critical minerals WASHINGTON, DC, UNITED STATES, June 16, 2026 / EINPresswire.com / - Phasecraft, the world's leading quantum algorithms company, today announced it has secured an award with the U.S. Department of Energy's Advanced Research Projects Agency-Energy (ARPA-E) to begin work under the Quantum Computing for Computational Chemistry (QC3) program. QC3 aims to accelerate energy innovation by supporting the development and application of quantum computing approaches to chemistry and materials science problems that lie beyond the reach of classical computers. The Collaboration Under the ~4.5M USD contract, Phasecraft will develop highly optimised quantum algorithms to simulate and discover novel catalysts for use in the energy sector. The project will aim to reduce the current reliance on critical minerals, in particular platinum group metals like iridium, that are used in catalysis. The initial focus is low-cost hydrogen production, with insights expected to apply across syngas production, petroleum refining, metallurgy, and other industrial sectors whose economics depend on the chemistry of catalysts. To complete this project, Phasecraft will partner with Johnson Matthey, Harvard, and QuEra. The approach builds on Phasecraft's published work in quantum materials simulation, where the company's algorithms have achieved efficiency improvements of up to 43,000,000x over previous quantum methods. "Quantum computing is no longer a distant promise. It's a working technology, and the question now is which problems it gets pointed at first," said Ashley Montanaro, Co-Founder and CEO of Phasecraft. "As industry and governments work together to realize the full promise of quantum computing, we are grateful that ARPA-E has chosen Phasecraft to help solve this critical set of problems on a meaningful timescale." "Hardware-adaptive quantum algorithms hold immense promise for priority problem sets across the U.S. government broadly, and the Department of Energy specifically," said Steve Flammia, Principal Quantum Scientist and head of Phasecraft US. "Cutting the iridium requirement in industrial electrolysis would meaningfully change the economics of hydrogen fuel and a wider class of catalytic processes that underpin energy security. Delivering significant quantum speed ups with hardware-adaptive algorithms could help shape iridium requirements in a matter of years, not decades." QC3 is part of a broader U.S. government effort to convert quantum computing's technical promise into competitive advantage in energy, the economy, and national security. The areas the program targets - superconducting transmission lines, advanced batteries, rare-earth-free magnets, and new catalysts for fuel production - sit at the foundations of a more secure and affordable American energy system. Algorithms designed to generate useful results from the imperfect quantum hardware available today, rather than from a future generation of machines, are central to delivering on that timeline. Phasecraft has a demonstrated track record of building ultra-efficient, hardware-adaptive algorithms that make practical quantum applications viable in the near-term and provide massive speed ups over the classical state of the art.
