Quantum Communication with Frequency 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.

Abstract

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.
