Projected logical ensembles in surface codes via the random-matrix theory of quantum dots
Mircea Bejan, Jan Behrends, Max McGinley +1
Measurements underpin active quantum error correction (QEC) and have been recognized as a source of novel measurement-induced many-body phenomena. Here, we study the statistical pr…

Spreading of Magic Resource under Unitary Clifford Dynamics
Mircea Bejan, Pieter W. Claeys, Jiangtian Yao
Nonstabilizerness, or quantum magic resource, presents a valuable resource in quantum error correction and computation. We study the dynamics of locally injected nonstabilizerness…

Matchgate circuits deeply thermalize
Mircea Bejan, Benjamin Béri, Max McGinley
We study the ensemble of states generated by performing projective measurements on the output of a random matchgate (or free-fermionic) quantum circuit. We rigorously show that thi…
