Coherence of quantum Gaussian channels (1908.04912v1)
Published 14 Aug 2019 in quant-ph
Abstract: Coherence is a basic notion for quantum states. Instead of quantum states, in this work, We establish a resource theory for quantifying the coherence of Gaussian channels. To do this, we propose the definitions of incoherent Gaussian channels and incoherent Gaussian superchannels.
