Manipulating the frequency-entangled states by an acoustic-optical modulator

Abstract

In this paper, we describe how to realize conditional frequency entanglement swapping and to produce probabilistically a three-photon frequency entangled state from two pairs of frequency entangled states by using an acoustic-optical modulator. Both schemes are very simple and may be implementable in practice.

Reply to the comment on `` Manipulating the frequency-entangled states by an acoustic-optical modulator''

B. S Shi, Yun-Kun Jiang, Guo, G. -C

In the paper [1], authors claim that the scheme for entanglement swapping using an acoustic-optical modulator [2] is flaw. In this reply, we show there is a trivial mistake in the scheme [2], but the main conclusion is still correct, that is, the acoustic-optical modulator can be used to manipulate the frequency-entangled state.

Comment on “Manipulating the frequency-entangled states by an acoustic-optical modulator”

A recent theoretical paper by Shi et al. [Phys. Rev. A 61, 064102 (2000)] proposes a scheme for entanglement swapping utilizing acousto-optic modulators without requiring a Bell-state measurement. In this Comment, we show that the proposal is flawed and no entanglement swapping can occur without measurement.

Teleporting a Frequency-entangled State via Acoustic-Optic Modulator

Xiang Shao

A scheme was presented for teleporting a frequencyentangled state with the successful probability 25 % based on the principle of the acousticoptic modulator(AOM).One advantage of the scheme is that no Bellstate measurement is need and no any unitary transformation is performed.

Scheme for Teleportation of an Unknown Frequency State by Using an Acousto-optical Modulator

Kehui Song

A very simple scheme is presented for teleporting an unknown frequency state with the successful probability of 50%. Two acoustic-optical modulators and four narrow band photodetectors in the proposed scheme are used. One advantage of our scheme is that no Bell-state measurement is need and no any unitary transformation is performed.

Generation of arbitrary symmetric entangled states with conditional linear optical coupling

A. V. Sharypov, Bing He

An approach to generating the entangled photonic states $|{\ensuremath{\Psi}}_{1},{\ensuremath{\Psi}}_{2}\ensuremath{\rangle}\ifmmode\pm\else\textpm\fi{}|{\ensuremath{\Psi}}_{2},{\ensuremath{\Psi}}_{1}\ensuremath{\rangle}$ from two arbitrary states $|{\ensuremath{\Psi}}_{1}\ensuremath{\rangle}$ and $|{\ensuremath{\Psi}}_{2}\ensuremath{\rangle}$ is proposed. The protocol is implemented by the conditionally induced beam-splitter coupling, which leads to the selective swapping between two photonic modes. Such coupling occurs in a quantum system prepared in the superposition of two ground states with only one of them being involved in the swapping. All the entangled states in the category, such as entangled pairs of coherent states or Fock states (NOON states), can be efficiently produced in the same way by this method.
