Classification: CPC H  G | IPC G  H

Claim 10:
11. A hub for a measurement-device-independent quantum key distribution network, comprising:
a wavelength-calibration laser;
an optical splitter configured to split an output of the wavelength-calibration laser into first and second wavelength-calibration signals;
a first optical output configured to transmit the first wavelength-calibration signal to a first node of the quantum key distribution network;
a second optical output configured to transmit the second wavelength-calibration signal to a second node of the quantum key distribution network; and
a Bell-state measurer configured to perform a Bell-state measurement with first and second photonic qubits received from the first and second nodes, respectively.
