Photonics quantum firm Orca Computing deploys PT-3 system at Digital Realty’s LHR19 data center

Described by the UK-based quantum firm as “the first quantum computer built for commercial advantage,” the PT-3 is modular and upgradable, weighing around 800kg (1,764lbs).

The system operates at room temperature, drawing 6kW of power across two standard data center racks.

Founded in 2019 as a spin-out from Oxford University, Orca Computing is a UK-based photonic quantum computing company.

The predecessor to the PT-3 system, the PT-2, was launched in 2024.

Prior to the PT-3 deployment, Digital Realty hosted an Orca PT-2 system at its liquid cooling lab at the LHR19 facility.
