Abstract

Using Bragg-scattering four-wave mixing, we prepare frequency-bin qubits and measure a purity of 0.92 through a lossy channel, suggesting viability for quantum networks using existing telecommunications infrastructure. Such a frequency-bin qubit obviates the polarization-compensation requirement of polarization qubits.

We demonstrate a quantum link employing frequency-bin qubits. Bragg-scattering four-wave mixing is used to encode and measure the qubit, and we obtain a 93% visibility over a 1-km communication channel without using active feedback to compensate for depolarization.
