A magic monotone for faithful detection of non-stabilizerness in mixed states
Krzysztof Warmuz, Ernest Dokudowiec, Chandrashekar Radhakrishnan +1
We introduce a monotone to quantify the amount of non-stabilizerness (or magic for short), in an arbitrary quantum state. The monotone gives a necessary and sufficient criterion fo…
