Questions tagged [resource-theories]

Any model of restricted quantum information processing built upon two main system-dependent requirements for the resources and allowed operations; (i) the existence of a set of states that are free and those not in the set are expensive; and (ii) the allowed operations are those that map the set of free states to itself.

Is there a resource theory of irreversibility?

We know that we can quantify the degree of irreversibility of a quantum process using the entropy production rate of the same process. But sometimes it seems that the very fact that information has ...

What is the relation between fidelity and concurrence for a two qubit maximally mixed state?

I am trying to understand the relation between Fidelity and Concurrence for a two qubit maximally mixed state. When I calculate the Fidelity and Concurrence, I observe that Concurrence is zero whereas ...
