Phasecraft builds ultra-efficient, hardware-agnostic quantum algorithms that pair quantum and classical computing to make Noisy Intermediate Scale Quantum (NISQ) devices useful for real-world applications. Its algorithms are designed from insights in theoretical physics and computer science and are validated through extensive numerical simulation and hardware partnerships. The company works with major quantum hardware providers including Google Quantum AI, IBM, Quantinuum, and QuEra to increase impact and portability. Phasecraft is already deploying solutions with end users such as Johnson Matthey, Oxford PV, the UK National Energy System Operator (NESO), and BT. Its work claims orders-of-magnitude efficiency improvements in materials simulation and applies quantum methods to biochemical processes and energy-network optimization. The company plans to double down on R&D breakthroughs and expand industrial efforts to build commercial solutions. Phasecraft develops quantum algorithms and partners with quantum hardware companies, academics, and industry leaders to move quantum computing from experimental demonstrations to useful applications. The company focuses early efforts on using algorithmic advances to discover novel materials for the clean energy transition. Phasecraft works with hardware partners including Google, IBM and Rigetti to tailor algorithms to current machines. The team was spun out of UCL and the University of Bristol and aims to build a larger team of quantum scientists, researchers and engineers. The company intends to use new funding to further develop its algorithms toward practical quantum advantage. Phasecraft builds quantum software and algorithms designed to reduce the quantum computing resources required for complex simulations, aiming to accelerate practical quantum applications. The company has developed an algorithm that significantly lowers the quantum power needed for calculations, which could enable new materials discovery. Founded by academics from the University of Bristol and UCL, the team includes internationally renowned quantum scientists Toby Cubitt, Ashley Montanaro and John Morton and currently employs around ten people. Phasecraft has established partnerships with quantum hardware companies such as Google and Rigetti and industry partner Johnson Matthey to help bridge hardware and applications. The startup’s stated goal is to advance quantum algorithms to bring commercial quantum applications forward by years. Financially, Phasecraft just closed a £3.7M seed round and has raised a total of £5.5M in venture funding and research grants to date.
