Abstract
Semiconductor quantum dots are prime candidates for quantum network applications such as quantum relays, but their typical emission wavelength, polarization qubit encoding scheme and low operating frequency are incompatible with existing technologies. Our work shows that InAs/InP quantum dots driven with GHz-clocked pulses, in combination with qubit transcoding interferometers, can bridge these gaps. The demonstrated teleportation of time-bin qubits in the telecom C band even when repetition rates exceed the inverse lifetime of the dot shows the potential for integrating such devices with long-distance quantum network technologies.
