Towards resource theory of coherence in distributed scenarios

Understand

The search for a simple description of fundamental physical processes is an important part of quantum theory.

• One example for such an abstraction can be found in the distance lab paradigm: if two separated parties are connected via a classical channel, it is notoriously difficult to characterize all possible operations these parties can perform.
• This class of operations is widely known as local operations and classical communication (LOCC).
• Surprisingly, the situation becomes comparably simple if the more general class of separable operations is considered, a finding which has been extensively used in quantum information theory for many years.
