Experimental demonstration of coherence flow in PT- and anti-PT-symmetric systems

The gain and loss inherent in non-Hermitian quantum systems can modify the flow of coherence between subsystems, which may be lost or recovered from the environment. Here, the coherence flow in PT-symmetric and anti-PT symmetric systems is investigated experimentally and theoretically.
