The general desire to break the symmetry of reciprocity in engineered photonic structures has garnered an immense amount of recent interest, as nonreciprocity is fundamental for the design of optical devices which allow for unidirectional routing of photonic signals. Especially, nonreciprocal microwave-frequency devices are crucial to efforts at quantum-information processing with superconducting circuits.
However, although nonreciprocal concepts are realizable in quantum architectures, nonreciprocity itself holds up to the classical level and is not inherently quantum; the fundamental aspects of nonreciprocity in the quantum regime have yet to be fully investigated. A first question one might ask is, if a nonreciprocal, and therewith as well dissipative, system can generate entanglement between it’s constituents? In this talk we will address this question and discuss under which conditions bi-bipartite system can generate entanglement.
