Quantum networking
Long-range quantum communication and distributed sensing.
Applications
Quantum light for systems, interfaces and research.
AQLS hardware supports the generation, conversion, storage and use of quantum states of light across a growing range of experiments.
Where AQLS technology fits
From single photons to connected quantum nodes.
Our products are designed around the physical interfaces between light, matter and optical-fibre infrastructure.
Photon-pair generation
Narrow-band entangled photon pairs provide a controlled optical resource for quantum-network experiments, atomic interfaces and connected research systems.
Frequency conversion
Frequency conversion translates photons between the wavelengths used by processors, memories and low-loss telecom-fibre channels.
Quantum memory research
Matched photon sources and memory platforms support experiments that store quantum states of light and retrieve them on demand.
Quantum communication
Entanglement-based light sources support protocols that distribute quantum information between fibre-connected nodes.
Quantum metrology
Stable, well-defined quantum light supports precision measurements in which sensitivity depends on photon statistics and coherence.
Quantum computing
Photonic interfaces can connect separated processors and distribute quantum states between modules in quantum-computing research.
Light–matter interaction
Narrow-band photons can be matched to atomic and solid-state transitions, enabling controlled interfaces between light and matter.
