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, UK. In 2023 we completed a £13m Series A funding round led by leading Silicon Valley deep tech VC, Playground Global, and in 2024 we opened our Washington DC office led by Steve Flammia.

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

Phasecraft Visiting Fellows share our team’s goal of making fundamental discoveries that accelerate the development of applied quantum computing. Visiting Fellows will spend an extended period of time (typically aro...
