Dynamical resource theory of quantum coherence
Gaurav Saxena, Eric Chitambar, Gilad Gour
Abstract
In this work, a resource theory of classical channels is developed. The authors examine the worst-case scenario of uploading and downloading quantum information from a cloud quantum computer. All quantum channels are true resources for quantum information processing, including the identity channel which preserves coherence
