Anticoncentration and nonstabilizerness spreading under ergodic quantum dynamics
Emanuele Tirrito, Xhek Turkeshi, Piotr Sierant
Quantum state complexity metrics, such as anticoncentration and nonstabilizerness, or ``magic'', offer key insights into many-body physics, information scrambling, and quantum comp…
Magic spreading in random quantum circuits
Xhek Turkeshi, Emanuele Tirrito, Piotr Sierant
Magic is the resource that quantifies the amount of beyond-Clifford operations necessary for universal quantum computing. It bounds the cost of classically simulating quantum syste…
Quantum Algorithms for Inverse Participation Ratio Estimation in multi-qubit and multi-qudit systems
Yingjian Liu, Piotr Sierant, Paolo Stornati +2
Inverse Participation Ratios (IPRs) and the related Participation Entropies quantify the spread of a quantum state over a selected basis of the Hilbert space, offering insights int…
Hilbert space delocalization under random unitary circuits
Xhek Turkeshi, Piotr Sierant
Unitary dynamics of a quantum system initialized in a selected basis state yields, generically, a state that is a superposition of all the basis states. This process, associated wi…
