Universal distributions of overlaps from generic dynamics in quantum many-body systems
Alexios Christopoulos, Amos Chan, Andrea De Luca
We study the distribution of overlaps with the computational basis of a quantum state generated under generic quantum many-body chaotic dynamics, without conserved quantities, for…

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…
