论文摘要
这项工作揭开了一个一维晶格模型的有趣特性,该模型描述了通过两种不同的非局部偶联机制,描述了与零维(无分散)玻色子耦合到零维(无分散)玻色子的有趣特性。也就是说,低于有效激发 - 玻色子耦合强度的临界值低于该模型的确切基态是裸露(即完全脱衣服)激发的零量化脉冲状态。这里证明了如何利用所考虑的晶格模型的最后一个属性,以在易于实现的电感耦合超导量子和微波谐振器的易于实现的系统中快速,确定性的准备。
This work unravels an interesting property of a one-dimensional lattice model that describes a single itinerant spinless fermion (excitation) coupled to zero-dimensional (dispersionless) bosons through two different nonlocal-coupling mechanisms. Namely, below a critical value of the effective excitation-boson coupling strength the exact ground state of this model is the zero-quasimomentum Bloch state of a bare (i.e., completely undressed) excitation. It is demonstrated here how this last property of the lattice model under consideration can be exploited for a fast, deterministic preparation of multipartite $W$ states in a readily realizable system of inductively-coupled superconducting qubits and microwave resonators.
