Floquet integrability and long-range entanglement generation in the one-dimensional quantum Potts model

Generating Symmetry-Protected Long-Range Entanglement in Many-Body Systems

“…Entanglement between spatially distant qubits is perhaps the most counterintuitive and vital resource for distributed quantum computing [1,2]. However, despite a few special cases [3][4][5][6][7], there is no known general procedure to maximally entangle two distant parts of an interacting many-body system. Here we present a symmetry-based approach, whereby one applies several timed pulses to drive a system to a particular symmetry sector with maximal bipartite long-range entanglement.…”
