Single-photon detectors (SPDs) are important devices in the development of quantum technologies, like quantum metrology, quantum computers and quantum communication. The simplest, cheapest and most commonly used SPD employs avalanche photodiode. After the photon absorption, a photocurrent is produced and it must be quenched before to damage the device. In the present work we show a new strategy for quenching the photocurrent of avalanche photodiodes remotely. Our scheme makes easier the synchronism between sender and receiver in a quantum communication setup. Some experimental results are presented.
