About ORCA Computing
ORCA Computing builds photonic quantum computers, which use particles of light as qubits and need less extreme cooling than superconducting designs. Its PT Series systems are designed to plug into existing data centre infrastructure. The company says it has deployed 11 systems in data centres worldwide and works with more than 35 enterprise and public sector partners. Its website lists NVIDIA, Digital Realty, Vodafone and the UK National Quantum Computing Centre among those it works with. The company is headquartered in London, United Kingdom.
ORCA Computing was founded in 2019 and is based in London, UK, United Kingdom. It is listed under Quantum Computing, Photonic Computing. Reported funding is $37M Series B (Nov 2025, NVentures/Temasek/Baillie Gifford/QIA).

What ORCA Computing works on
Quantum Computing
A quantum computer is a machine that uses the rules of quantum physics to process information. Its basic unit is the qubit. A classical bit is either 0 or 1. A qubit can be in a superposition, a state that combines both, and its measured result is probabilistic.
Photonic Computing
Photonic computing uses light instead of electricity to carry or process information. Photons have no charge, so light in a waveguide does not cause the resistive heating that current in a wire does, though lasers and modulators still use power, and many wavelengths can share one waveguide. The industry has two quite different parts: moving data with light, and computing with light.
