波导介导纠缠中的非马尔可夫效应

Non-Markovian effects in waveguide-mediated entanglement

C. Gonzalez-Ballestero, F. J. Garcia-Vidal, Esteban Moreno

摘要:

我们研究了通过一维波导模耦合的两个量子比特之间纠缠的产生和演化。通过使用一个完整的量子电动力学形式主义,我们超越了马尔可夫近似。对哈密顿量进行对角化,得到了一组准定域本征态,并指出随着量子比特-波导耦合的增加,马尔可夫近似不再成立,纠缠的产生变得更糟.

英文摘要:

We study the generation and evolution of entanglement between two qubits coupled through one-dimensional waveguide modes. By using a complete quantum electrodynamical formalism we go beyond the Markovian approximation. The diagonalization of the hamiltonian is carried out, and a set of quasi-localized eigenstates is found. We show that when the qubit-waveguide coupling is increased, the Markov approximation is not anymore valid, and the generation of entanglement is worsened.
