Variational optimization of the quantum annealing schedule for the Lechner-Hauke-Zoller scheme
Yuki Susa, Hidetoshi Nishimori
The annealing schedule is optimized for a parameter in the Lechner-Hauke-Zoller (LHZ) scheme for quantum annealing designed for the all-to-all-interacting Ising model representing…
Two-parameter counter-diabatic driving in quantum annealing
Luise Prielinger, Andreas Hartmann, Yu Yamashiro +3
We introduce a two-parameter approximate counter-diabatic term into the Hamiltonian of the transverse-field Ising model for quantum annealing to accelerate convergence to the solut…
Tunable optomechanically induced transparency by controlling the dark-mode effect
Deng-Gao Lai, Xin Wang, Wei Qin +3
We study tunable optomechanically induced transparency by controlling the dark-mode effect induced by two mechanical modes coupled to a common cavity field. This is realized by int…
Nonclassical Preparation of Quantum Remote States
Shih-Hsuan Chen, Yu-Chien Kao, Neill Lambert +2
Remote state preparation (RSP) enables a sender to remotely prepare the quantum state of a receiver without sending the state itself. Recently, it has been recognized that quantum…
Nonreciprocal ground-state cooling of multiple mechanical resonators
Deng-Gao Lai, Jin-Feng Huang, Xian-Li Yin +5
The simultaneous ground-state cooling of multiple degenerate or near-degenerate mechanical modes coupled to a common cavity-field mode has become an outstanding challenge in cavity…
Liouvillian exceptional points of any order in dissipative linear bosonic systems: Coherence functions and switching between and anti- symmetries
Ievgen I. Arkhipov, Adam Miranowicz, Fabrizio Minganti +1
Usually, when investigating exceptional points (EPs) of an open Markovian bosonic system, one deals with spectral degeneracies of a non-Hermitian Hamiltonian (NHH), which can corre…
