在非惯性系中处于热库中的两个腔的纠缠动力学
《物理学报》2014年第2期9-14,共6页梁艳 吴奇成 计新 
国家自然科学基金(批准号:11064016)资助的课题~~
研究了非惯性系中处于热库中的两个腔的纠缠动力学.不仅考虑了加速参数对纠缠的影响,还考虑了Unruh单粒子态左右成分之间的不同比率对纠缠的影响.结果表明:加速参数一定时,随着腔间纠缠的减少,热库间的纠缠将会增加;此外,当初始状态为...

相位阻尼通道下初始纠缠对纠缠演化的影响被引量:1
《物理学报》2012年第23期47-50,共4页刘其功 计新 
国家自然科学基金(批准号:11064016;61068001)资助的课题~~
研究了在非惯性系中相位阻尼通道下初始纠缠对纠缠演化的影响.结果发现:与振幅阻尼通道情况不同,当态参数不同而初始纠缠相同时,纠缠演化曲线重合.当Unruh单粒子态包含左右成分时,比只包含右成分时量子消相干现象更加严重,较早地出现了...

Generating a four-photon polarization-entangled cluster state with homodyne measurement via cross-Kerr nonlinearity
《Chinese Physics B》2012年第4期308-314,共7页苏石磊 王媛 郭奇 王洪福 张寿 
supported by the National Natural Science Foundation of China (Grant Nos. 61068001 and 11064016)
We propose a protocol to generate a four-photon polarization-entangled cluster state with cross-Kerr nonlinearity by using the interference of polarized photons. The protocol is based on optical elements, cross-Kerr n...

Deterministic implementations of fermionic quantum SWAP and Fredkin gates for spin qubits based on charge detection
《Chinese Physics B》2012年第4期92-96,共5页王洪福 张寿 朱爱东 
supported by the National Natural Science Foundation of China (Grant Nos. 11147174, 61068001, 11165015, and 11064016);the Talent Program of Yanbian University of China (Grant No. 950010001)
We propose a scheme to implement fermionic quantum SWAP and Fredkin gates for spin qubits with the aid of charge detection. The scheme is deterministic without the need of qubit–qubit interaction, and the proposed se...

Implementation of nonlocal Bell-state measurement and quantum information transfer with weak Kerr nonlinearity
《Chinese Physics B》2011年第12期72-78,共7页白娟 郭奇 程留永 邵晓强 王洪福 张寿 Yeon Kyu-Hwang 
supported by the National Natural Science Foundation of China (Grant Nos. 61068001 and 11064016)
We propose a protocol to implement the nonlocal Bell-state measurement, which is nearly determinate with the help of weak cross-Kerr nonlinearities and quantum non-destructive photon number resolving detection. Based ...

Measurement-induced disturbance and nonequilibrium thermal entanglement in a qutrit qubit mixed spin XXZ model被引量:1
《Chinese Physics B》2011年第10期78-84,共7页陈丽 邵晓强 张寿 
supported by the National Natural Science Foundation of China (Grant Nos. 61068001 and 11064016)
We investigate the dynamics of nonequilibrium thermal quantum correlation of a qutrit-qubit mixed spin system coupled to two bosonic reservoirs at different temperatures using measurement-induced disturbance. The effe...
