Nothing is scheduled on hope.
Q-Memory is a UK company designing programmable, room-temperature photonic processors for quantum research labs today and quantum data centers tomorrow. This page sets out what exists today, what comes next, and what has to be proven in between.
Where we are today
| Company | Q-Memory Limited, registered in the UK |
|---|---|
| Fabrication partner | Sabancı University Nanotechnology Research and Application Center (SUNUM), in collaboration |
| Intellectual property | UK patent application filed in June 2026 (on record). Patent pending. |
| Phase 1 test chip | Design completed and reviewed with SUNUM, our fabrication partner. Fabrication is planned in a multi-project wafer (MPW) run, with first chips planned for winter 2026–27. |
| Phase 2 | A larger processor aimed at quantum research labs, designed toward rack integration. Foundry selection follows the Phase 1 results. |
| Long term | Toward quantum data centers, and classical optical processing on the same platform. |
What we are working on now
- Phase 1 fabrication with SUNUM. Our Phase 1 chip is planned for fabrication in a multi-project wafer (MPW) run, in collaboration with Sabancı University Nanotechnology Research and Application Center (SUNUM). First chips are planned for winter 2026–27.
- A chip that measures itself. Dozens of on-chip test structures mean the first run will tell us how the processor performs, and why.
- The memory layer. Developing our patent-pending memory layer, which is designed to hold settings at near-zero power.
- Early access. Speaking with research groups about testing and first applications.
The first measured results from our own hardware will come from this run, and we will publish them.
The roadmap
Each phase builds on measured results from the one before. Our milestones are measured performance, not calendar dates.
Phase 1: first test chip
A four-channel programmable light processor that proves the platform works as well as the simulations say.
Status: Now. Design completed and reviewed with SUNUM, our fabrication partner; fabrication is planned in a multi-project wafer (MPW) run. First chips are planned for winter 2026–27.
Phase 2: larger processor for quantum research labs
A room-temperature processor designed toward rack integration.
Status: Builds on the validated Phase 1 platform. Foundry selection follows the Phase 1 results.
Phase 3 and beyond: toward quantum data centers
Processors for quantum data centers, and classical optical processing on the same platform.
Status: Long term.
Phase 1 performance benchmarks
| Test | Question it answers | Goal |
|---|---|---|
| Quantum interference | Can two single photons meet on the chip and interfere as quantum physics predicts? | > 90% (target) |
| Programming accuracy | When we ask for an operation, how close does the chip get? | < 1% (target) |
| Stability | How far do the settings drift over time? | < 5 mrad/min (target) |
Meeting these benchmarks confirms the platform is ready to scale to Phase 2. They are targets today, and we will publish the measured results.
Manufacturing
The chip is made with chip-industry methods: wafer-scale lithography on a low-loss material that is well established for photonics. We work with university and commercial fabrication partners, chosen for each phase. For Phase 1 we collaborate with SUNUM, where our chip is planned for fabrication in a multi-project wafer (MPW) run.
Next to the processor, the test chip carries dozens of small test structures, so one fabrication run tells us not only whether the processor works, but why.
Our approach
- Honest numbers. We label goals as goals and publish measurements when we have them.
- Small, proven steps. Each phase is validated against measured performance benchmarks before the next begins.
- Independent. We choose university and commercial fabrication partners for each phase.
- Based in the UK, working with international partners.
