Abstract
Quantum key distribution (QKD) requires high synchronization accuracy,
specially in systems that use gated detectors at the receiver station. In
this work, we present a reference clock distribution method to support long-term QKD. An average quantum bit error rate (QBER) of 1.8% was measured, which is suitable for different QKD implementations. This method is suitable for long distance and long-term QKD implementations and does not require additional transmitted qubits for synchronization.
