About the Company

Phasecraft

Designs hardware-efficient quantum algorithms

Phasecraft designs quantum algorithms that reduce the hardware needed to solve hard problems, aiming to move closer to quantum advantage by lowering qubit counts and circuit depth. It tests and refines its algorithms with leading hardware partners such as Google, IBM, Rigetti, Quantinuum and QuEra to co-develop solutions for enterprise clients in fields like materials science, pharmaceuticals and telecommunications. A notable product is THRIFT, an algorithm that speeds up dynamic quantum simulations by about 10x, enabling larger and longer-running runs on near-term quantum processors. Their goal is to bridge the gap between current quantum hardware limits and future fault-tolerant machines by providing practical, hardware-efficient quantum software and intellectual property through collaborations and IP development.
