Construction and simulability of quantum circuits with free fermions in disguise
Dávid Szász-Schagrin, Daniele Cristani, Lorenzo Piroli +1
We provide a systematic construction for local quantum circuits hosting free fermions in disguise, both with staircase and brickwork architectures. Similar to the original Hamilton…
Breaking global symmetries with locality-preserving operations
Michele Mazzoni, Luca Capizzi, Lorenzo Piroli
In the general framework of quantum resource theories, one typically only distinguishes between operations that can or cannot generate the resource of interest. In many-body settin…
Learning mixed quantum states in large-scale experiments
Matteo Votto, Marko Ljubotina, Cécilia Lancien +5
We present and test a protocol to learn the matrix-product operator (MPO) representation of an experimentally prepared quantum state. The protocol takes as an input classical shado…
The Hilbert-space structure of free fermions in disguise
Eric Vernier, Lorenzo Piroli
Free fermions in disguise (FFD) Hamiltonians describe spin chains which can be mapped to free fermions, but not via a Jordan-Wigner transformation. Although the mapping gives acces…
Entanglement dynamics and Page curves in random permutation circuits
Dávid Szász-Schagrin, Michele Mazzoni, Bruno Bertini +2
The characterization of ensembles of many-qubit random states and their realization via quantum circuits are crucial tasks in quantum-information theory. In this work, we study the…
Adiabatic quantum state preparation in integrable models
Maximilian Lutz, Lorenzo Piroli, Georgios Styliaris +1
We propose applying the adiabatic algorithm to prepare high-energy eigenstates of integrable models on a quantum computer. We first review the standard adiabatic algorithm to prepa…
Entanglement asymmetry dynamics in random quantum circuits
Filiberto Ares, Sara Murciano, Pasquale Calabrese +1
We study the dynamics of entanglement asymmetry in random unitary circuits (RUCs). Focusing on a local charge, we consider symmetric initial states evolved by both local one…
