Quantum-to-Classical Computability Transition via Negative Markov Chains
Hugo Lóio, Jacopo De Nardis, Tony Jin
We develop a recently introduced representation of quantum dynamics based on sampling negative Markov chain processes. By introducing particles and antiparticles, this formalism ma…
Quantum State Designs via Magic Teleportation
Hugo Lóio, Guglielmo Lami, Lorenzo Leone +3
We investigate how non-stabilizer resources enable the emergence of quantum state designs within the projected ensemble. Starting from initial states with finite magic and applying…
Field theory for monitored Brownian SYK clusters
Anastasiia Tiutiakina, Hugo Lóio, Guido Giachetti +2
We consider the time evolution of multiple clusters of Brownian Sachdev-Ye-Kitaev (SYK), i.e. systems of N Majorana fermions with a noisy interaction term. In addition to the unita…
Correlations, Spectra and Entanglement Transitions in Ensembles of Matrix Product States
Hugo Lóio, Guillaume Cecile, Sarang Gopalakrishnan +2
We investigate ensembles of Matrix Product States (MPSs) generated by quantum circuit evolution followed by projection onto MPSs with a fixed bond dimension . Specifically, we…
