论文摘要
多体量子系统中的模式纠缠是一个积极的研究领域。它为多体系统对量子信息处理任务的适用性提供了关键的见解。在评估物理上可接近的纠缠量时，必须考虑当地的超级选择规则。这需要通过纳入局部奇偶校验和局部粒子数约束来修改公认的纠缠措施。在本文中，我们报告了N-Harmonium的分析解决系统中存在的模式纠缠。据作者的了解，这是对连续状态空间中相互作用多体系统的物理访问模式和模式模式纠缠的首次分析研究。我们发现，超选择规则大大减少了物理上可接近的纠缠量，这在某些情况下完全消失了。我们的结果强烈表明需要在其他费米子和骨系统系统中重新评估内部和模式间纠缠。
Mode entanglement in many-body quantum systems is an active area of research. It provides crucial insight into the suitability of many-body systems for quantum information processing tasks. Local super-selection rules must be taken into account when assessing the amount of physically accessible entanglement. This requires amending well-established entanglement measures by incorporating local parity and local particle number constraints. In this paper, we report on mode entanglement present in the analytically solvable system of N-Harmonium. To the knowledge of the authors, this is the first analytic study of the physically accessible mode and mode-mode entanglement of an interacting many-body system in a continuous state space. We find that super-selection rules dramatically reduce the amount of physically accessible entanglement, which vanishes entirely in some cases. Our results strongly suggest the need to re-evaluate intra and inter-mode entanglement in other fermionic and bosonic systems.
