论文摘要
我们提供了一个指导原则，以通过将希格斯机制的关键思想应用于没有规格结构的系统来产生量子多体状态的纠缠。与Higgs机制相关的单一操作员是构建的，称为均值操作员，并被用来使纠缠的多体状态从琐碎的状态中做好准备。我们在平方晶格上揭示了一个具有两个Ising对称性的对称性保护状态，并找到具有不同对称性和晶格的纠缠状态。还讨论了量子模拟器（例如Rydberg原子和被困离子）的合理应用，将均值操作器解释为Ising耦合门。
We provide a guiding principle to generate entanglement of quantum many-body states by applying key ideas of the Higgs mechanism to systems without gauge structures. Unitary operators associated with the Higgs mechanism are constructed, named as mean-operators, and employed to prepare entangled many-body states out of a trivial state. We uncover a symmetry-protectedtopological state with two Ising symmetries on a square lattice and find entangled states with different symmetries and lattices. Plausible applications to quantum simulators such as Rydberg atoms and trapped ions, are also discussed, interpreting the mean-operators as the Ising coupling gates.
