We introduce a method to measure many-body magic in quantum systems based on a
statistical exploration of Pauli strings via Markov chains. We demonstrate that sampling such …

The classical simulation of highly entangling quantum dynamics is conjectured to be
generically hard. Thus, recently discovered measurement-induced transitions between …

We propose to use a quantum spin chain as a device to store and release energy coherently
and we investigate the interplay between its internal correlations and outside decoherence …

Stabilizer entropies (SEs) are measures of nonstabilizerness or “magic” that quantify the
degree to which a state is described by stabilizers. SEs are especially interesting due to their …

Stabilizer entropies (SE) measure deviations from stabilizer resources and as such are a
fundamental ingredient for quantum advantage. In particular, the interplay of SE and …

Notions of nonstabilizerness, or “magic,” quantify how nonclassical quantum states are in a
precise sense: states exhibiting low nonstabilizerness preclude quantum advantage. We …

Magic is a property of a quantum state that characterizes its deviation from a stabilizer state,
serving as a useful resource for achieving universal quantum computation eg, within …

Stabilizer entropy (SE) quantifies the spread of a state in the basis of Pauli operators. It is a
computationally tractable measure of nonstabilizerness and thus a useful resource for …

Quantum systems can not be efficiently simulated classically due to the presence of
entanglement and nonstabilizerness, also known as quantum magic. Here we study the …

We study different aspects of the stabilizer entropies (SEs) and compare them against
known nonstabilizerness monotones such as the min-relative entropy and the robustness of …
