Abstract

为经由拉曼相互作用产生簇状态的一个计划被建议。Inthe 计划，我们第一准备多洞的簇状态，信息编码了为协调状态然后产生多原子的簇状态，它把信息编码为Λ - 类型原子的扎根的状态。我们的计划的优点是原子自发的放射能高效地被减少自从洞频率大部分是从原子转变频率的 detuned，协调状态的 Hadamard 门操作被测量协调状态代替。

A Scheme for Generating Cluster States via Raman Interaction

Rong‐Can Yang, LI Hong-cai, Lin Xiu +2 more

A scheme for generating cluster states via Raman interaction is proposed. In the scheme, we firstly prepare cluster states of multi-cavities with information encoded in the coherent states and then generate cluster states of multi-atoms, which encode the information in the ground states of Λ-type atoms. The advantages of our scheme are that the atomic spontaneous radiation can be efficiently reduced since the cavity frequency is largely detuned from the atomic transition frequency and the Hadamard gate operation of the coherent states is replaced by measuring the coherent states.

Phase Conjugation Progress in Ensemble of Double-Lambda Atoms

Rozhdestvensky, Yury

Recently experiments on investigation of four wave mixing in sodium vapor cell have been performed by group of Dr P. Hemmer. It has been shown in these experiments that generation of a phase-conjugate wave takes place at large detuning of a pumping wave from the resonant transition in a double Lambda system of atomic levels only (so called case of Raman interaction). Moreover, the experiments demonstrated high efficiency of such Raman interaction for generation of the conjugate wave with low intensities of the exciting waves that indicates realization of new type of Raman laser. The aim of our work is theoretical analysis and numerical simulation of the experiment on the basis of exact solution of self-consistent system of Maxwell-Bloch equations. The atom-field interaction scheme is shown in the report. A peculiarity of this scheme is that the same pumping wave interacts with both transitions 1 ---> 3 and 2 ---> 4 simultaneously.

Single-channel Hadamard gate by exploiting frequency conversion of single-photon Raman scattering in chiral quantum nanophotonics

Zihao Chen, Yao Zhou, Jung‐Tsung Shen

To enhance the spatial utility of typical two-port Hadamard gate, we propose a novel single-channel scheme through frequency conversion in Λ-atom-mediated single-photon Raman scattering process in chiral quantum nanophotonics. We demonstrate faithful and efficient gate operations, and quantitatively analyze gate performance. Moreover, by manipulating photon-emitter coupling and frequency detuning, it is confirmed that an arbitrary unitary single-qubit operations are achieved in the presented configuration, including most representative single-qubit Hadamard, X, Z, S, and T gates. Due to the advent of directional emission techniques, the chiral condition is readily experimentally feasible. In addition, we further propose an alternative N-type atom architecture to perform Hadamard operations that are enabled by hyperfine structure in the strong-coupling regime.
