Universal purification dynamics of monitored Clifford circuits
Beatrice Magni, Federico Gerbino, Xhek Turkeshi +1
Quantum circuits under sufficiently weak monitoring purify on a timescale exponentially long in the system size. This slowness underlies a universal purification dynamics, wh…
Non-Local Magic Resources for Fermionic Gaussian States
Daniele Iannotti, Beatrice Magni, Riccardo Cioli +2
Entanglement and magic are fundamental resources that capture the complexity of quantum many-body systems. Non-local magic isolates the irreducible nonstabilizerness intrinsically…
Quantum Complexity and Chaos in Many-Qudit Doped Clifford Circuits
Beatrice Magni, Xhek Turkeshi
We investigate the emergence of quantum complexity and chaos in doped Clifford circuits acting on qudits of odd prime dimension . Using doped Clifford Weingarten calculus and a…
Anticoncentration and State Design of Doped Real Clifford Circuits and Tensor Networks
Beatrice Magni, Markus Heinrich, Lorenzo Leone +1
We investigate the statistical properties of orthogonal, or real, Clifford circuits doped with magic and imaginary resources. By developing the Weingarten calculus for the real Cli…
Anticoncentration in Clifford Circuits and Beyond: From Random Tensor Networks to Pseudo-Magic States
Beatrice Magni, Alexios Christopoulos, Andrea De Luca +1
Anticoncentration describes how an ensemble of quantum states spreads over the allowed Hilbert space, leading to statistically uniform output probability distributions. In this wor…
Universality in the Anticoncentration of Chaotic Quantum Circuits
Arman Sauliere, Beatrice Magni, Guglielmo Lami +2
We identify a \emph{universal functional form} that governs anticoncentration in random quantum circuits-one that holds across diverse circuit architectures and depths, and crucial…
