标题： Tradeoff between extractable mechanical work, accessible entanglement, and ability to act as a reference system, under arbitrary superselection rules

摘要： 超选择规则（SSRs）限制了由量子态表示的机械和量子处理资源。 然而，可以使用参考系统来打破基础对称性，从而违反SSRs。 我们表明，系统进行机械做工的能力与其作为参考系统的能力之间存在对偶性。 此外，对于处于全局对称纯态的双粒子系统，我们发现系统进行局部机械做工的能力、由于其可获取纠缠而进行“逻辑做工”的能力以及作为共享参考系统的能力之间存在三重性。 显示英文摘要

摘要： Superselection rules (SSRs) limit the mechanical and quantum processing resources represented by quantum states. However SSRs can be violated using reference systems to break the underlying symmetry. We show that there is a duality between the ability of a system to do mechanical work and to act as a reference system. Further, for a bipartite system in a globally symmetric pure state, we find a triality between the system's ability to do local mechanical work, its ability to do ``logical work'' due to its accessible entanglement, and its ability to act as a shared reference system.
