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 |
|---|---|
| Intellectual property | UK patent application filed in June 2026 (on record). Patent pending. |
| Phase 1 test chip | Design completed and reviewed with our fabrication partner; fabrication being scheduled. First chips are 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 has not been done yet
No chip has been fabricated. We have no measurements from our own hardware, no customers, and no revenue. Figures on this site marked as goals are aims, not results.
The roadmap
Each phase starts only when the chip before it passes its measured go/no-go tests. Gates are measurements, 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 our fabrication partner; fabrication being scheduled. 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: Starts when Phase 1 passes all three go/no-go tests. 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.
The three go/no-go tests for Phase 1
| 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) |
We move to Phase 2 only if the chip passes all three. These are goals, not results. We will publish the measured numbers, whatever they are.
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.
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 has go/no-go tests; we do not skip ahead.
- Independent. We choose university and commercial fabrication partners for each phase.
- Based in the UK, working with international partners.
