Q-Memory Photonic Quantum Processor
A CMOS-compatible silicon quantum processor that runs at room temperature — delivering programmable linear optical quantum computing, AI matrix acceleration at the speed of light
The Power of Q-Memory
How Q-Memory Delivers Results — Step by Step
Fire a particle of light
Like flipping a coin and placing it face-down — you know it's there but haven't looked at it yet.
Steer it through a grid of adjustable mirrors
The photon travels along glass channels thinner than a spider's silk thread.
Make two photons permanently linked
When two photons arrive at the same mirror at exactly the same instant, quantum physics forces them to entangle
Catch the photon
At the exit, a detector cooled catches each photon
Act on the result
The detection result feeds back into the chip within 10 nanoseconds

No Power Wasted Holding the Chip Still
Typically, mirrors require a steady supply of electricity to maintain their position—similar to keeping your foot on the gas pedal to maintain a constant speed. However, we use a unique material that can hold its setting without needing any continuous power. In a chip with 256 mirrors, this can save 490 watts, which is equivalent to turning off 40 desk lamps that have been on all day just to keep the chip stable.
One Chip — Two Ways to Generate Functions
The same mirror network that runs quantum calculations also runs the maths behind every AI model — at the speed of light, using roughly 100× less electricity than a classic GPU. If the quantum product takes longer than expected, the AI acceleration product still generates output.
Use Cases & Applications
From today’s lab demonstrations to tomorrow’s fault-tolerant quantum advantage
Quantum ML — Predictions from Noise
Traditional AI systems often require tens of thousands of training examples to recognize and learn complex patterns. In contrast, our 64-mode photonic chip achieves comparable learning performance using as few as 70 samples — dramatically reducing training time, energy consumption, and computational overhead.
Quantum Data Centre — Rack-Scale Photonic Computing
Today’s AI data centres running large language models draw 2 MW per compute cluster — that is, roughly 2,800 high-end server GPUs running flat-out, burning enough electricity to power 2,000 family homes around the clock. A rack of 32 Phase 3 photonic processors does the same matrix work using just 40 kW
The Quantum Internet
The same chip routes quantum logic gates and distributes entangled photon pairs across fibre at 1550 nm — the wavelength existing telecoms infrastructure already carries. The model is validated, heralded entanglement between two quantum memory nodes over fibre with 15× temporal multiplexing at 510 coincidences/s — the exact architecture this chip interconnects.
Unbreakable Communications
Entangled photon pairs generated on-chip create encryption keys that obey the laws of physics — any eavesdropper disturbs the quantum state and is instantly detected. The paper demonstrated integrated photonic QKD that exceeded the PLOB repeaterless bound over 370 km of fibre using this exact chip platform.
