Abstract

A novel secure quantum key distribution scheme using EPR pairs is presented. It has three distinct features: 1) it is very efficient. Unlike existing quantum key distribution schemes, this scheme uses all EPR pairs in distributing the key except those chosen for checking eavesdroppers; 2) this protocol has high capacity because each EPR pair carries 2 bits of key code while existing schemes carry only one bit of key code; 3) this scheme can be used for distributing a common key among arbitrary number of parties.

Theoretically efficient high-capacity quantum-key-distribution scheme

Gui‐Lu Long, X. S. Liu

A theoretical quantum key distribution scheme using Einstein-Podolsky-Rosen (EPR) pairs is presented. This scheme is efficient in that it uses all EPR pairs in distributing the key except those chosen for checking eavesdroppers. The high capacity is achieved because each EPR pair carries 2 bits of key code.

A Scheme about Quantum Key Distribution Between Two Users

Ding He-wei

A quantum key distribution scheme using EPR pairs between two parties is proposed.In this scheme,Alice and Bob measure the state using Bell base and operate it using R(θ) for checking eavesdroppers during distributing the key.It is more efficient in that one uses all EPR pairs except those chosen for checking eavesdroppers.As the key,it can be proved to be secure.

EFFICIENT QUANTUM KEY DISTRIBUTION SCHEME USING THE BELL STATE MEASUREMENT

Xiaoyu Li

In this paper we provide a quantum key distribution (QKD) scheme based on the correlations of Einstein–Podolsky–Rosen (EPR) pairs. The scheme uses an auxiliary qubit to interact with the EPR pair and does the Bell state measurement to get the key. It is proved to be secure. All EPR pairs are used in distributing the key except some error-checking bits. So it is efficient. On the other hand there are less classical communications needed in the scheme.

Quantum key distribution based on entanglement swapping

Adán Cabello

Entanglement swapping between EPR pairs can be used to generate the same sequence of random bits in two remote places. A quantum key distribution protocol based on this idea is described. The scheme exhibits the following features: (a) It improves the rate of generated bits for transmitted qubit. (b) It allows Alice and Bob to generate a key of arbitrary length using a single quantum system (three EPR pairs), instead of a long sequence of them. (c) Detecting Eve requires the comparison of fewer bits. (d) Entanglement is an essential ingredient. The scheme assumes reliable measurements of the Bell operator.

Secure Communication Based on Single Photon States

Yan Feng-Li

A quantum key distribution and secure communication scheme using single photon states between two parties is proposed.It is more efficient in that it uses all single photon states in distributing the key except those chosen for checking eavesdroppers.In addition,security of the developed secure communication scheme could reach the one-time-pad level.
