Quantum interconnects that scale computing beyond a single cryostat

Microwave quantum processors break records — but they are hard to scale within one fridge. Miraex quantum converters bridge to the optical domain so processors can be linked into a cluster over standard telecom fibre.
The missing link

Bridge stationary and flying qubits

The energies of stationary qubits (microwave photons) and flying qubits (optical photons) differ by five orders of magnitude. Miraex quantum converters bridge that gap — transferring quantum information over long distances between microwave-frequency processing units using classical optical telecom fibre.

On the roadmap

Where we’re taking the interconnect

Directions we are actively developing toward — beyond today’s superconducting focus.
Trapped-ion & cold-atom scale-upExtending optical interconnects toward architectures targeting 100–1,000s of qubits across these modalities.
Space & dual-use applicationsExploring compact, radiation-tolerant links for satellite and defence deployments.
