Description
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.

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

To support this we are looking to hire a HR Business Partner to join our team as a trusted advisor to our founders, managers and staff, delivering outstanding people support while helping us scale effectively and sustainably.
