Quantum technologies / quantum/quantum-interconnect
Quantum interconnect
Channels that carry quantum states or entanglement between quantum processors in separate cryostats or modules, so that a machine can grow past what one cryostat holds.
Scope
In scope: links between modules of a superconducting machine, such as microwave-to-optical transduction and optical entanglement distribution, and their fidelity and rate. Out of scope: long-distance quantum networks and communication for their own sake, and on-chip couplers inside a module.

Dependencies
Requires
- Photonic integration Optical links between modules need low-loss waveguides, modulators and detectors integrated on chip.
Required by
- Fault-tolerant quantum computer A machine of up to a million qubits is unlikely to fit in one cryostat, so modules must be linked by quantum channels.
Holds open
- Links between modulesFault-tolerant quantum computer
