Despite the enormous theoretical and experimental progress made so far in quantum key
distribution (QKD), the security of most existing practical QKD systems is not rigorously …

Although quantum key distribution (QKD) is theoretically secure, there is a gap between the
theory and practice. In fact, real-life QKD may not be secure because component devices in …

There is a large gap between theory and practice in quantum key distribution (QKD)
because real devices do not satisfy the assumptions required by the security proofs. Here …

Quantum key distribution (QKD) guarantees unconditional communication security based on
the laws of quantum physics. However, practical QKD suffers from a number of quantum …

To guarantee the security of quantum key distribution (QKD), security proofs of QKD
protocols have assumptions on the devices. Commonly used assumptions are, for example …

Quantum key distribution (QKD) based on the laws of quantum physics allows the secure
distribution of secret keys over an insecure channel. Unfortunately, imperfect …

Measurement-device-independent quantum key distribution (MDI-QKD) is immune to all
security loopholes on detection. Previous experiments on MDI-QKD required spatially …

In theory, quantum key distribution (QKD) offers information-theoretic security. In practice,
however, it does not due to the discrepancies between the assumptions used in the security …

The security of quantum key distribution (QKD) is severely threatened by discrepancies
between realistic devices and theoretical assumptions. Recently, a significant framework …

The performance of quantum key distribution (QKD) is severely limited by multiphoton
emissions, due to the photon-number-splitting attack. The most efficient solution, the decoy …
