Generalized hydrodynamics of integrable quantum circuits
Friedrich Hübner, Eric Vernier, Lorenzo Piroli
Quantum circuits make it possible to simulate the continuous-time dynamics of a many-body Hamiltonian by implementing discrete Trotter steps of duration . However, when is s…
Approximate inverse measurement channel for shallow shadows
Riccardo Cioli, Elisa Ercolessi, Matteo Ippoliti +2
Classical shadows are a versatile tool to probe many-body quantum systems, consisting of a combination of randomised measurements and classical post-processing computations. In a r…
Monitored fermions with conserved charge
Michele Fava, Lorenzo Piroli, Denis Bernard +1
We study measurement-induced phases of free fermion systems with U(1) symmetry. Following a recent approach developed for Majorana chains, we derive a field theory description for…
Integrability of Goldilocks quantum cellular automata
Logan E. Hillberry, Lorenzo Piroli, Eric Vernier +3
Goldilocks quantum cellular automata (QCA) have been simulated on quantum hardware and produce emergent small-world correlation networks. In Goldilocks QCA, a single-qubit unitary…
Approximating many-body quantum states with quantum circuits and measurements
Lorenzo Piroli, Georgios Styliaris, J. Ignacio Cirac
We introduce protocols to prepare many-body quantum states with quantum circuits assisted by local operations and classical communication. We show that by lifting the requirement o…
Strong zero modes in integrable quantum circuits
Eric Vernier, Hsiu-Chung Yeh, Lorenzo Piroli +1
It is a classic result that certain interacting integrable spin chains host robust edge modes known as strong zero modes (SZMs). In this work, we extend this result to the Floquet…
