The safety of a quantum key distribution system relies on the fact that any eavesdropping attempt on the quantum channel creates errors in the transmission. For a given error rate, the amount of information that may have leaked to the eavesdropper depends on both the particular system and the eavesdropping strategy. In this work, we discuss quantum cryptographic protocols based on the transmission of weak coherent states and present a system, based on a symbiosis of two existing systems, for…

Quantum Secure Direct Communication Based on Secret Initial States of EPR Pairs

This paper proposes the protocol of Quantum Secure Direct Communization (QSDC) based on the secret initial Bell states which are shared by two legitimate communicators. Then, we analyze the security

Unconditional security of practical quantum key distribution

This paper is identical to the preprint arXiv:quant-ph/0107017, which was finalized in 2001, therefore, some of the more recent developments, including the question of composability, are not addressed.

Effect of channel imperfection on the secrecy capacity of a quantum cryptographic system

This work presents a semiempirical relation between the fully secure throughput and the loss and noise levels in the channel, and suggests that an implementation of BB84 utilizing commercially available detectors can reach throughputs as high as 104-105 secure bits per second over a practical channel of reasonable quality.

Security of the decoy state method for quantum key distribution

The decoy state method is devoted to, a countermeasure against vulnerabilities caused by the use of coherent states of light for QKD protocols whose security is proved under the assumption of single-photon states.

Defense frontier analysis of quantum cryptographic systems.

The amount of data sacrifice sufficient to defend against individual eavesdropping attacks in both BB84 and B92 protocols is derived and it is concluded that the BB84 protocol may offer better performance characteristics than the B92.

Quantum key distribution against Trojan horse attacks

It is shown that quantum communication may be improved with quantum teleportation and entanglement swapping, which is robustly secure against the most general Trojan horse attacks.

Effect of finite detector efficiencies on the security evaluation of quantum key distribution

Quantum key distribution with the Bennett-Brassard 1984 protocol has been shown to be unconditionally secure even using weak coherent pulses instead of single-photon signals. The distances that can

Quantum Key Distribution with Imperfect Devices

In this Chapter we outline some of the experimental flaws that allow a potential eavesdropper to successfully breach the security of a QKD protocol. We then focus on the solutions to such problems,

Quantum cryptography for secret key generation using frequency-division long-distance interferometry

This work presents a semi-empirical relation between the fully-secure throughput and the loss and noise levels in the channel, and suggests that a particular implementation of BB84, based on the frequency-division multiplexing scheme and utilizing commercially available detectors, can reach throughputs as high as 104 - 105 secure bits per second over a practical channel of reasonable quality.

The security and recent technology of quantum key distribution

The decoy-state method and the entanglement-distribution method can be used to realize the unconditionally secure QKD based on real-life systems with existing technology.
