Q/C Technologies Names Yossef Ehrlichman Chief Technology Officer to Lead Optical Processor Development

Q/C Technologies names a new CTO to drive its silicon photonics-based optical processor and integrated photonics development roadmap.

Rhea-AI Summary

Q/C Technologies (QCLS) has appointed Yossef (“Yossi”) Ehrlichman, Ph.D., as Chief Technology Officer to lead its optical processing unit (OPU) program and overall technology strategy, effective after his joining earlier in 2026 as founding manager of photonic integrated circuit (PIC) development.

Dr. Ehrlichman has 15 years of experience in silicon photonic integrated circuits across device design, foundry process development and volume production. He is a named inventor on U.S. patents for linearized optical digital-to-analog conversion and multi-electrode micro-ring devices, which are described as central building blocks of the company’s OPU architecture. Q/C Technologies describes a staged, milestone-driven approach to developing integrated photonics systems that keep data in optical form for more of the computation and aim toward integrating optical processing and memory in a complete platform. The company plans to update shareholders as milestones are reached.

silicon photonic architecture technical

"Proprietary silicon photonic architecture targets critical bandwidth"

A silicon photonic architecture is the engineered layout and combination of light-guiding components—waveguides, modulators, detectors, lasers (sometimes off-chip), and electronic interfaces—built on silicon to move and process optical signals on a chip. It matters to investors because the architecture determines how fast, power-efficient, scalable, and cost-effective an optical product or chip line can be, much like a building’s floor plan affects how many people it can serve and how efficiently they move through it.

optical processing unit technical

"will now lead the Company's optical processing unit (OPU) program"

An optical processing unit is a computer chip that uses light rather than electric signals to carry out calculations, often for tasks like machine learning, image or signal processing. Because light can move and be manipulated very quickly with less heat, OPUs can handle huge amounts of data faster and more efficiently than conventional chips; investors care because OPUs could lower operating costs, speed up AI workloads and create competitive advantages for companies that adopt or produce them.

photonic integrated circuit technical

"founding manager of photonic integrated circuit (PIC) development"

A photonic integrated circuit is a tiny chip that routes and processes light signals instead of electrical currents, like an electronic microchip but built to use photons. It matters to investors because these chips can make data transmission and sensing much faster, more energy-efficient and cheaper at scale, potentially enabling new high-growth products and cutting operating costs across communications, computing and sensing industries.

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."

About Q/C Technologies, Inc.
