“…Comparing to our previous results [23], the quantum efficiency of the detector drops down from 20% to 13.8% with almost the same dark count probability. And this is due to the addition of the analog switch, which modifies the shape of the gate pulse and especially increases its rising and falling times (see Fig.…”

“…The active hold-off technique prevents the occurrence of afterpulses and then can be approvingly compared to the afterpulse-discarding method of A. Yoshizawa et al [15,24], which only permits to postselect the avalanche signals of sufficiently large number of adjacent pulses after every photon click event. The measured results on some key parameters of SPD demonstrate that the active hold-off technique can efficiently enhance the noise-efficiency performance of the detector [14,23]. However, full characterization of SPD with active hold-off technique is still necessary to better understand the improvements it provided.…”

“…One simple technique used to suppress the afterpulse noise in InGaAs/InP APDs is called the active hold-off technique [14,23]. The principle of this technique is to hold-off an appropriate number of gate pulses immediately following an avalanche event, giving the trapped carriers a time to dissipate, so that afterpulses become negligible (see Fig.…”

“…If a photon click occurs in a certain pulse, the probability to have one or more photon clicks within the next few gate pulses immediately following the avalanche is very low (see [13]). In such a case, it seems suitable to hold-off on an appropriate number of gate pulses after each registered detection click.…”

Physical implementations of quantum key distribution (QKD) protocols, like the Bennett-Brassard (BB84), are forced to use attenuated coherent quantum states, because the sources of single photon states are not functional yet for QKD applications. However, when using attenuated coherent states, the relatively high rate of multi-photonic pulses introduces vulnerabilities that can be exploited by the photon number splitting (PNS) attack to brake the quantum key. Some QKD protocols have been developed to be resistant to the PNS attack, like the decoy method, but those define a single photonic gain in the quantum channel. To overcome this limitation, we have developed a new QKD protocol, called ack-QKD, which is resistant to the PNS attack. Even more, it uses attenuated quantum states, but defines two interleaved photonic quantum flows to detect the eavesdropper activity by means of the quantum photonic error gain (QPEG) or the quantum bit error rate (QBER). The physical implementation of the ack-QKD is similar to the well-known BB84 protocol.

We report a near infrared (NIR) single photon detector (SPD) using an InGaAs/InP avalanche photodiode (APD) operated with a bipolar rectangular gating signal. The use of the bipolar gating pulse enabled us to operate the APD well below the breakdown voltage during the gate-off time. As a result, it permits to decrease the lifetime of the trapped carriers, and then reduces the after-pulse noise of the detector. At a repetition rate of 200 MHz, the after-pulse probability is 8.2% less comparing to that of conventional gating signal SPD.
