Lead Quantum Algorithms Scientist

Phasecraft is the quantum algorithms company. We are building the mathematical foundations for quantum computing applications that solve real‑world problems. Founded in 2019 by Toby Cubitt, Ashley Montanaro and John Morton, we are based in London and Bristol in the UK and opened an office in Washington DC in 2024, led by Steve Flammia. In 2023 we completed a $17m Series A funding round led by leading Silicon Valley deep tech VC, Playground Global.

Phasecraft's unprecedented access to today's best quantum computers – through partnerships with Google, IBM, Quantinuum and QuEra – provides us with unique opportunities to develop foundational IP, inform the development of next‑generation quantum hardware, and accelerate commercialization of high‑value breakthroughs.
