Swapping Floquet time crystal
Roberto Gargiulo, Gianluca Passarelli, Procolo Lucignano +1
We propose a Floquet period-doubling time-crystal model based on a disordered interacting long-range spin chain where the periodic swapping of nearby spin couples is applied. This…
Convergence of Digitized-Counterdiabatic QAOA: circuit depth versus free parameters
Mara Vizzuso, Gianluca Passarelli, Giovanni Cantele +1
Recently, Digitized-Counterdiabatic (CD) Quantum Approximate Optimization Algorithm (QAOA) has been proposed to make QAOA converge to the solution of an optimization problem in few…
Many-body Dynamics in Monitored Atomic Gases Without Post-Selection Barrier
Gianluca Passarelli, Xhek Turkeshi, Angelo Russomanno +3
We study the properties of a monitored ensemble of atoms driven by a laser field and in the presence of collective decay. The properties of the quantum trajectories describing the…
Parent Hamiltonian Reconstruction via Inverse Quantum Annealing
Davide Rattacaso, Gianluca Passarelli, Angelo Russomanno +3
Finding a local Hamiltonian having a given many-body wavefunction as its ground state, i.e. a parent Hamiltonian, is a challenge of fundamental impo…
Counterdiabatic Reverse Annealing
Gianluca Passarelli, Procolo Lucignano
We present Counterdiabatic Reverse Annealing, a novel quantum annealing protocol that extends the range of application of reverse annealing to the previously inaccessible short-tim…
