Dynamical Resources

Understand

Quantum channels are quintessential to quantum information, being used in all protocols, and describing how systems evolve in space and time.

• As such, they play a key role in the manipulation of quantum resources, and they are often resources themselves, called dynamical resources.
• This forces us to go beyond standard resource theories of quantum states.
• Here we provide a rigorous foundation for dynamical resource theories, where the resources into play are quantum channels, explaining how to manipulate dynamical resources with free superchannels.
