Phasecraft is taking quantum theory from research to reality, faster. Phasecraft was founded in 2019 by Toby Cubitt, Ashley Montanaro, and John Morton, expert quantum scientists who have spent decades leading top research teams at UCL and the University of Bristol.

Phasecraft collaborates with leading quantum hardware companies, including Google, IBM, and Rigetti, academic and industry leaders, to develop high-efficiency quantum algorithms and software that evolve quantum computing from experimental demonstrations to useful applications.

The Phasecraft journey so far:

2019: spinout founded between UCL and the University of Bristol
2023: Series A raised of £13 million
2025: Raised $34 million Series B.
