Quantum computing (QC) is an emerging paradigm with the potential to offer significant
computational advantage over conventional classical computing by exploiting quantum …

Although the unconditional security of quantum key distribution (QKD) has been widely
studied, the imperfections of the practical devices leave potential loopholes for Eve to spy …

The passive approach to quantum key distribution (QKD) consists of removing all active
modulation from the users' devices, a highly desirable countermeasure to get rid of …

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

Decoy-state measurement-device-independent quantum key distribution (MDI-QKD) is
regarded as one of the most promising protocols since it is physically immune to all fatal …

Lithium niobate (Li Nb O 3, LN) devices play critical roles in quantum information
processing. However, for special applications like quantum key distribution (QKD), the …

A commercial quantum key distribution (QKD) system needs to be formally certified to
enable its wide deployment. The certification should include the system's robustness against …

A passive quantum key distribution (QKD) transmitter generates the quantum states
prescribed by a QKD protocol at random, combining a fixed quantum mechanism and a post …

Unconditionally secure communication, which has been pursued for thousands of years
hasn't, however, yet been reached due to a continuous competition between encryption and …

A well-protected and characterized source in a quantum key distribution system is needed
for its security. Unfortunately, the source is vulnerable to light-injection attacks, such as …
