Quantum Information Processing Without Joint Measurement

Yang Ming, Zhuo‐Liang Cao

Published May 22, 2005• 0 citations

Abstract

We propose a linear optical scheme for the teleportation of unknown ionic states, the entanglement concentration for nonmaximally entangled states for ions via entanglement swapping and the remote preparation for ionic entangled states. The unique advantage of the scheme is that the joint Bell-state measurement needed in the previous schemes is not needed in the current scheme, i.e. the joint Bell-state measurement has been converted into the product of separate measurements on single ions and photons. In addition, the current scheme can realize the quantum information processes for ions by using linear optical elements, which simplify the implementation of quantum information processing for ions.

Quantum teleportation by entanglement swapping with trapped ions

Zheng Xiao-Juan, Mao-Fa Fang, Cai Jian-Wu +1 more

An effective teleportation scheme for an unknown ionic internal state via trapped ions is proposed without joint Bell-state measurement (BSM). In the constructed quantum channel process, we make use of entanglement swapping to avoid decrease in entanglement during the distributing of particles. Thus our scheme provides new prospects for quantum teleportation in a longer distance. The distinct advantage of our scheme is insensitive to the heating of vibrational mode. Furthermore, our scheme has no any individual optical access and the successful probability also can reach 1.

Teleportation for an Ionic Entangled Internal State by Entanglement Swapping

Zheng Xiao-Juan, Mao-Fa Fang, Xiang-Ping Liao +1 more

We present an effective scheme to teleport an unknown ionic entangled internal state via trapped ions without joint Bell-state measurement. In the constructed quantum channel process, we adopt entanglement swapping to avoid decrease of entanglement during the distribution of particles. Thus our scheme provides new prospects for quantum teleportation over longer distance. The distinct advantages of our scheme are that our scheme is insensitive to heating of vibrational mode and can be generalized to teleport an N -ion electronic entangled GHZ class state. Furthermore, in our scheme the success probability can reach 1.

Entanglement purification for arbitrary unknown ionic states via linear optics

Ming Yang, Wei Song, Zhuo‐Liang Cao

An entanglement purification scheme for arbitrary unknown (mixed and pure nonmaximally) entangled ionic states is proposed by using linear optical elements. The main advantage of the scheme is that not only two-ion maximally entangled pairs but also four-ion maximally entangled pairs can be extracted from the less entangled pairs. The scheme is within current technology.

Teleportation of Multi-ionic GHZ States and Arbitrary Bipartite Ionic State via Linear Optics

Jian Zhou, Dong Ping, Zhuo‐Liang Cao

We present a scheme for teleportation of multi-ionic GHZ states and arbitrary bipartite ionic state only by single-qubit measurements via linear optical elements. In our scheme, we avoid the difficulty of joint measurement and synchronizing the arrival time of the two scattered photons, which are faced by previous schemes. So our scheme can be realized easily within current experimental technology.
