Differential-phase-shift (DPS) quantum key distribution (QKD) is one of the major QKD
protocols that can be implemented with a simple setup using a laser source and a passive …

In theory, quantum key distribution (QKD) allows secure communications between two
parties based on physical laws. However, most of the security proofs of QKD today make …

Measurement-device-independent quantum key distribution (MDI-QKD) can remove all
detection side-channels from quantum communication systems. The security proofs require …

Security proofs of quantum key distribution (QKD) typically assume that the devices of the
legitimate users are perfectly shielded from the eavesdropper. This assumption is, however …

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 …

We consider in this paper the practical implementation of a siftingless quantum key
distribution protocol. The protocol is considered siftingless since it combines sifting and error …

Unlike traditional communication, quantum key distribution (QKD) can reach unconditional
security and thus attracts intensive studies. Among all existing QKD protocols, round-robin …

Modern telecommunications networks are based on packet-switching traffic processing and
the methodology by which packets can be delivered using an arbitrary route. However, for …

New protocol to achieve very long-distance and secure communication between two
legitimate users (Alice and Bob) namely, the pseudo-random entangled photon based QKD …

The main goal of this research project is to analyse the security of practical implementations
of discrete-variable QKD systems. While it is true that in theory QKD can offer unconditional …
