Space-Quantum is building Europe's first orbital quantum computing data centre — where the vacuum is the cryostat, the Sun is the grid, and the qubits finally get the silence they were promised.
A qubit is the most delicate object humans have ever tried to control. On Earth, almost everything works against it — heat, vibration, gravity-bound cooling limits, and a relentless background of energy. Orbit removes the obstacles instead of engineering around them.
Qubits need millikelvin temperatures. In the shadow of a radiator panel, deep space sits near 3 K with no atmosphere to fight. Cooling becomes radiative, not just refrigerated — slashing the energy cost of the coldest stage.
Seismic micro-vibration, traffic, HVAC, and footsteps all decohere qubits. A free-flying platform in microgravity is mechanically silent in a way no terrestrial basement can ever match.
In the right orbit the Sun never dips below a horizon. Multi-junction solar arrays harvest unfiltered sunlight 24/7 — no clouds, no night, no atmospheric losses, no land footprint.
Away from terrestrial RF noise and with isolation impossible to buy on the ground, control signals stay clean — improving gate fidelity at the physical layer rather than correcting for it.
Every constraint that makes terrestrial quantum data centres expensive — cooling, isolation, energy, real estate — is something space simply hands you. We stop spending watts to recreate the cosmos and start operating inside it.
How we get thereA staged path that de-risks the hardest parts first — power and cooling — before scaling the quantum payload.
