Generation of atomic entangled states using linear optics

Abstract

In this paper, we propose a novel scheme that can generate two-atom maximally entangled states from pure product states and mixed states using linear optics. Because the scheme can generate pure maximally entangled states from mixed states, we denote it as purification-like generation scheme.

Generation of pure ionic entangled states via linear optics

Ming Yang, Zhuo‐Liang Cao

In this paper, we propose a scheme to generate two-ion maximally entangled states from either pure product states or mixed states using linear optics. Our new scheme is mainly based on the ionic interference. Because the proposed scheme can generate pure maximally entangled states from mixed states, we denote it as a purificationlike generation scheme. The scheme does not need a Bell state analyzer as the existing entanglement generation schemes do, it also avoids the difficulty of synchronizing the arrival time of the two scattered photons faced by the existing schemes, thus the proposed new entanglement generation scheme can be implemented more easily in practice.

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.

Maximally entangled mixed states made easy

Andrea Aiello, Graciana Puentes, J. P. Woerdman

We show how to generate maximally entangled mixed states of two photons from the singlet state by using local linear-optical channels and postselection. Both theoretical predictions and experimental findings are presented.

Scheme for purifying a general mixed entangled state and its linear optical implementation

Dong Dong, Yan‐Lei Zhang, Chang‐Ling Zou +2 more

We propose a scheme for purification of a general mixed entangled state. In this scheme, we start from a large number of general mixed entangled states and end up, after local operation and classical communication, with a smaller number of Bell diagonal states with higher entanglement. In particular, the scheme can purify one maximally entangled state from two entangled pairs prepared in a class of mixed entangled state. Furthermore we propose a linear optical implementation of the present scheme with polarization beam splitters and photon detectors.

Generation and purification of maximally entangled atomic states in optical cavities

Pavel Lougovski, E. Solano, HERBERT WALTHER

We present a probabilistic scheme for generating and purifying maximally entangled states of two atoms inside an optical cavity via no-photon detection at the cavity output, where ideal detectors are not required. The intermediate mixed states can be continuously purified so as to violate Bell inequalities in a parametrized manner. The scheme relies on an additional strong-driving field that realizes, atypically, simultaneous Jaynes-Cummings and anti-Jaynes-Cummings interactions.

The generation of an entangled four-photon state from two pairs of entangled two-photon states by using linear optical elements

Xu‐Bo Zou, K. Pahlke, Wolfgang M. Mathis

We present a scheme to produce an entangled four-photon state from two pairs of entangled two-photon states. Such entangled four-photon states are equivalent to the quantum state of two maximally entangled spin-1 particles. The scheme can also be generated to prepare an entangled 2N-photon state from N pairs of entangled two-photon states. Such multi-photon states play a crucial role in fundamental tests of quantum mechanics versus local realism and in many quantum information and quantum computation schemes.
