Theoretically efficient high-capacity quantum-key-distribution scheme

Abstract

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.

An Efficient High Capacity Quantum Key Distribution Scheme

Gui‐Lu Long, Xiao Shu Liu

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.

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.

A Theoretical Scheme for Multi—user Quantum Key Distribution with N Einstein—Podolsky—Rosen Pairs on a Passive Optical Network

Fu‐Guo Deng, 刘晓曙

We propose a theoretical scheme for any-to-any multi-user quantum key distribution on a passive optical network with ordered N Einstein-Podolsky-Rosen Pairs.This scheme is safe and more efficient than those with single photons.Its efficiency approaches 100% in the limit that the number of pairs used in the eavesdropping check becomes negligible.It also has high capacity and is convenient for users.

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.

Quantum key distribution without alternative measurements

Adán Cabello

Entanglement swapping between Einstein-Podolsky-Rosen (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 does not require that Alice and Bob choose between alternative measurements, therefore improving the rate of generated bits by 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.
