Stephanie Simmons

Develops silicon spin–photon technology and helped found Photonic, bringing quantum information stored in silicon together with optical links for distributed quantum computing.

Simmons works at the interface between storing quantum information and transmitting it. Her research on silicon spin–photon systems underpins Photonic’s approach to connecting qubits optically, and she leads the company’s technical vision as Chief Quantum Officer. That combination of local quantum memory and remote connection is central to a distributed architecture. Her profile therefore focuses on the physical interface and the organization she helped create, without treating prospective scale or fault tolerance as demonstrated achievements.
