Understanding Quantum Networks.

Quantum computers and quantum sensors will become more useful when they can exchange quantum information. AQLS develops physical hardware intended to help connect otherwise incompatible systems and support the wider development of quantum networks.

A quantum network connects quantum processors, sensors or memories and allows quantum information to be distributed between them. Doing this requires specialised sources, wavelength interfaces, transmission channels, memories and detectors.

They can support distributed quantum computing, remote sensing and communication protocols whose security is based on quantum physics. Larger distances and multiple users require network architectures and physical hardware beyond a direct point-to-point link.

AQLS focuses on room-temperature operation, narrow-band light, fibre interfaces and robust optical architectures. Source wavelengths and connector configurations can be adapted to the systems they need to interface with.

The current portfolio brings together an entangled photon-pair source, a quantum frequency converter and a room-temperature quantum memory platform. Current technology readiness levels are 7 for the entangled photon-pair source, 4–5 for the quantum frequency converter and 3–4 for the quantum memory.

Many system requirements depend on wavelength, bandwidth, fibre connection and the hardware on either side of the interface. Contact the team with your application so the appropriate configuration can be discussed.
