Intracity Quantum Communication via Thermal Microwave Networks: Sketch of a thermal quantum network, where two nodes (for example, two superconducting qubits located inside separated dilution refrigerators) are connected via a unidirectional quantum communication channel at finite temperature T ch . (b) For the implementation of a noise-resilient transfer protocol, the qubit state is first mapped onto an intermediary oscillator. The oscillator is then coupled to the incoming and outgoing fields of the channel, f in , i ( t ) and f out , i ( t ) , via a tunable decay rate γ i ( t ) , which can be realized, for example, by a flux-tunable quantum interference device [45, 46, 47].
