Programmable light processors, built for the quantum era.

Q-Memory designs programmable, room-temperature photonic processors: chips that steer and mix light under software control. We build them for quantum research labs today and quantum data centers tomorrow, with AI acceleration on the same platform.

Light inResultTunable interferometers
How a programmable photonic processor works. Software sets each tunable interferometer, so the same chip performs a different operation, reconfigured in software. An illustration of the principle.

What we are building

A photonic processor is a network of tiny light paths on a chip. Where paths meet, a tunable interferometer decides how much light goes each way. Set all of them from software and the chip performs a chosen operation on the light passing through. Change the settings and it performs a different one, on the same chip.

Room temperature

The processor chip runs at room temperature. Single-photon detectors, where an experiment uses them, sit in a compact cooler.

Programmable

One chip, many experiments, reconfigured in software.

Made with chip-industry methods

Wafer-scale lithography on a low-loss material that is well established for photonics.

How the chip works

VION in your browser

VION is our first product: a four-channel programmable light processor. Our online simulator runs the VION design, so you can program it before the first chips exist.

  • Set each phase shifter and watch the light re-route through the mesh.
  • Pick a target operation and let the simulator program the chip to match it.
  • Swap lasers, photon sources and detectors on a virtual lab bench.
  • Try a new virtual chip: each one carries its own fabrication imperfections.

Try the simulatorSee what it does

The VION simulator: light from a laser travels through a mesh of six tunable interferometers to four detectors, with phase settings on the left and detected light and the transfer map on the right.

A memory layer for light

Today’s programmable photonic chips hold each setting by continuously heating a small part of the chip. That costs power, produces heat, and makes the chip drift.

Our memory layer (patent filed) is designed to hold settings at near-zero power, for processors that are more stable and lower-power, which matters when many chips share a rack.

Where the work stands

VION is planned for fabrication in collaboration with Sabancı University Nanotechnology Research and Application Center (SUNUM). First chips are planned for December 2026.

A roadmap built on measured results

Each phase builds on measured results from the one before, so every step rests on proven performance.

  1. VION: our first programmable processor

    A four-channel programmable light processor that proves the platform works as well as the simulations say.

  2. AXIOM: one chip for quantum and AI

    A larger programmable processor that runs quantum circuits, quantum machine learning and AI acceleration on the same chip.

  3. Next phase and beyond: toward quantum data centers

    Processors for quantum data centers, and classical optical processing on the same platform.
