Phasecraft designs quantum algorithms that lower the number of qubits and the depth of quantum circuits needed to solve complex problems. Its algorithms are tested and refined through partnerships with leading hardware providers like Google, IBM, Rigetti, Quantinuum and QuEra, so they work on real processors. The company focuses on near-term quantum computers to enable larger and longer-running simulations in areas such as materials science, chemistry and network optimization. Its goal is to bridge the gap between today’s noisy devices and fault-tolerant quantum machines by delivering practical, hardware-efficient quantum software and related IP.

Simplify's Take

What believers are saying

  • September 2025 Series B raised $34 million, bringing total funding above $50 million.
  • June 2026 ARPA-E awarded Phasecraft roughly $4.5 million for catalyst discovery.
  • June 2026 Atom Computing MOU and March 2026 DARPA QBI expand validation channels.

What critics are saying

  • DARPA QBI expects utility-scale quantum by 2033; failure kills Phasecraft's premise.
  • Quantum computing revenue stays contract-driven; 2025-2026 partnerships still lack recurring product sales.
  • Competitors like Quantinuum, QuEra, and Atom Computing own hardware attention and budgets.

What makes Phasecraft unique

  • Ashley Montanaro, Toby Cubitt, and John Morton give Phasecraft elite academic credibility.
  • Mondrian, launched October 2025, targets optimization with up to 1,000x speedups.
  • Phasecraft pairs hardware-adaptive algorithms with Google, IBM, QuEra, and Atom Computing.

Phasecraft tapped by ARPA-E to develop and apply quantum algorithms for catalyst discovery.

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.
