Multi-spin counter-diabatic driving in many-body quantum Otto refrigerators
Andreas Hartmann, Victor Mukherjee, Glen Bigan Mbeng +2
Quantum refrigerators pump heat from a cold to a hot reservoir. In the few-particle regime, counter-diabatic (CD) driving of, originally adiabatic, work-exchange strokes is a promi…
Reinforcement Learning assisted Quantum Optimization
Matteo M. Wauters, Emanuele Panizon, Glen B. Mbeng +1
We propose a reinforcement learning (RL) scheme for feedback quantum control within the quan-tum approximate optimization algorithm (QAOA). QAOA requires a variational minimization…
Polynomial scaling of QAOA for ground-state preparation of the fully-connected p-spin ferromagnet
Matteo M. Wauters, Glen Bigan Mbeng, Giuseppe E. Santoro
We show that the quantum approximate optimization algorithm (QAOA) can construct with polynomially scaling resources the ground state of the fully-connected p-spin Ising ferromagne…
Optimal quantum control with digitized Quantum Annealing
Glen Bigan Mbeng, Rosario Fazio, Giuseppe E. Santoro
We show how a digitized version of Quantum Annealing can be made optimal, realizing the best possible solution allowed by quantum mechanics in the shortest time, without any prior…
Optimal working point in digitized quantum annealing
Glen Bigan Mbeng, Luca Arceci, Giuseppe E. Santoro
We present a study of the digitized Quantum Annealing protocol proposed by R. Barends et al., Nature 534, 222 (2016). Our analysis, performed on the benchmark case of a transverse…
Quantum Annealing: a journey through Digitalization, Control, and hybrid Quantum Variational schemes
Glen Bigan Mbeng, Rosario Fazio, Giuseppe Santoro
We establish and discuss a number of connections between a digitized version of Quantum Annealing (QA) with the Quantum Approximate Optimization Algorithm (QAOA) introduced by Farh…
