From maximum work to maximum power in an optimally controlled quantum Ising Otto engine
Vincenzo Roberto Arezzo, Davide Rossini, Giuseppe E. Santoro +1
In finite-time quantum Otto engines, maximizing power requires balancing the duration of the unitary strokes against the losses from nonadiabatic excitations. We address this trade…
Parity Mapping for Quantum Optimization on Frustrated Ising Rings
Ruiyi Wang, Anita Weidinger, Glen Bigan Mbeng +2
The frustrated Ising ring is one of the simplest models exhibiting exponential closing spectral gaps, making it a paradigmatic and challenging benchmark for quantum annealing (QA).…
Digital techniques for the frustrated Ising ring: the role of counter-diabatic terms
Kiran Thengil, Vincenzo Roberto Arezzo, Giuseppe E. Santoro
We investigate the role of local counter-diabatic (CD) terms in enhancing the performance of discrete-time digital protocols for a frustrated Ising ring, a system with an exponenti…
Continuous-time quantum control across an exponentially small bottleneck in a frustrated Ising ring model
Vincenzo Roberto Arezzo, Kiran Thengil, Giuseppe Santoro
Continuous-time Quantum Annealing (QA) is a strategy for preparing the ground state of nontrivial many-body systems. In its standard form, the dynamics is generated by a time-depen…
