Non-Hermitian topology in driven-dissipative systems: correspondence with quantum correlations and a resource for entanglement

Directional amplification, in which signals are amplified selectively depending on their propagation direction, is a key resource for quantum information processing and stands in one-to-one correspondence with non-trivial non-Hermitian topology. So far, this correspondence has concerned the mean fields, and thus classi...
