Proprietary silicon photonic architecture targets critical bandwidth, energy efficiency and 
scalability demands of AI inference

Optical processors aim to cut the energy and bandwidth cost of moving data in AI systems

SAN FRANCISCO, Sept. 15, 2026 (GLOBE NEWSWIRE) -- Q/C Technologies, Inc. (Nasdaq: QCLS) (“Q/C Technologies” or “the Company”), a developer of next-generation optical computing solutions, today announced the appointment of Chief Technology Officer Yossef (“Yossi”) Ehrlichman, Ph.D. Dr. Ehrlichman joined the Company earlier this year as founding manager of photonic integrated circuit (PIC) development and will now lead the Company's optical processing unit (OPU) program and overall technology strategy.

Dr. Ehrlichman brings 15 years of experience developing and commercializing silicon photonic integrated circuits, spanning device design, foundry process development and volume production. He is a named inventor on issued U.S. patents covering linearized optical digital-to-analog conversion and multi-electrode micro-ring devices — two of the building blocks central to the Company's OPU architecture.

“Scaling optical computing for AI means addressing the energy and time spent moving data and converting signals between electronics and optics,” said Dr. Ehrlichman. “Our integrated photonics program is developing the components needed to keep data in optical form through more of the computation and bring those components together into scalable systems. These efforts lay the foundation for our long-term goal of integrating optical processing and memory in a complete computing platform. We are taking a staged approach, with clear milestones, and I look forward to reporting our progress.”

"Yossi combines deep silicon photonics experience with a disciplined, milestone-driven engineering approach, and he has already built the foundation of an exceptional team that we are continuing to expand," said Executive Chairman Joshua Silverman. "With Yossi leading our integrated photonics track alongside our optical AI model for image generation, Q/C Technologies is pursuing optical computing from two complementary directions. We will update shareholders as the program reaches each of its defined milestones."
