Yamen Hamdouni

摘要:

两个相互作用的量子比特,其中每个是嵌入在自己的自旋星浴的动力学的精确分析结果。研究了有限和无限环境自旋下两量子比特系统的纠缠度和纯度随时间的演化。研究了量子比特间相互作用对中心系统稳态的影响

英文摘要:

Exact analytical results for the dynamics of two interacting qubits each of which is embedded in its own spin star bath are presented. The time evolution of the concurrence and the purity of the two-qubit system is investigated for finite and infinite numbers of environmental spins. The effect of qubit-qubit interactions on the steady state of the central system is investigated
