Phasecraft

Phasecraft is a quantum algorithms company building software that combines classical and quantum computing to solve real-world problems in materials discovery, advanced biochemistry, and optimization. Its algorithms are engineered to run efficiently across multiple quantum hardware platforms, and its published results include scalable approaches to the Fermi-Hubbard model and QAOA-based optimization. Founded by Profs. Ashley Montanaro (CEO) and Toby Cubitt (CTO), the company operates from London, Bristol, and Washington DC, and is backed by Playground Global. Phasecraft exposes no public developer API; its programmatic surface is limited to open research code on GitHub and two interactive web tools (a materials database and an optimization graph library).

Phasecraft is profiled on the APIs.io network. Tagged areas include Company, Compute, Quantum Computing, Quantum Algorithms, and Materials Discovery.

Phasecraft’s developer surface includes support and 7 more developer resources.
