On nonlocality as a resource theory and nonlocality measures

Understand

With the advent of device independent quantum information processing, nonlocality is nowadays regarded as a resource to implement various tasks.

• On the analogy of entanglement theory we approach nonlocality from this perspective.
• In order to do so, we analyze in full detail the operations that can be implemented in this scenario and under which nonlocality cannot increase.
• This provides a theoretical ground to study how to order and quantify nonlocal behaviours.
