Efficient estimation of trainability for variational quantum circuits
Valentin Heyraud, Zejian Li, Kaelan Donatella +2
Parameterized quantum circuits used as variational ansätze are emerging as promising tools to tackle complex problems ranging from quantum chemistry to combinatorial optimization.…
Dynamics with autoregressive neural quantum states: application to critical quench dynamics
Kaelan Donatella, Zakari Denis, Alexandre Le Boité +1
Despite very promising results, capturing the dynamics of complex quantum systems with neural-network ansätze has been plagued by several problems, one of which being stochastic no…
Noisy Quantum Kernel Machines
Valentin Heyraud, Zejian Li, Zakari Denis +2
In the noisy intermediate-scale quantum era, an important goal is the conception of implementable algorithms that exploit the rich dynamics of quantum systems and the high dimensio…
Non-Gaussian superradiant transition via three-body ultrastrong coupling
Fabrizio Minganti, Louis Garbe, Alexandre Le Boité +1
We introduce a class of quantum optical Hamiltonian characterized by three-body couplings, and propose a circuit-QED scheme based on state-of-the-art technology that implements the…
Continuous-time dynamics and error scaling of noisy highly-entangling quantum circuits
Kaelan Donatella, Zakari Denis, Alexandre Le Boité +1
We investigate the continuous-time dynamics of highly-entangling intermediate-scale quantum circuits in the presence of dissipation and decoherence. By compressing the Hilbert spac…
Metastability in the driven-dissipative Rabi model
Alexandre Le Boité, Myung-Joong Hwang, Martin B. Plenio
We explore the long-time dynamics of Rabi model in a driven-dissipative setting and show that, as the atom-cavity coupling strength becomes larger than the cavity frequency, a new…
Fate of photon blockade in the deep strong coupling regime
Alexandre Le Boité, Myung-Joong Hwang, Hyunchul Nha +1
We investigate the photon emission properties of the driven-dissipative Rabi model in the so-called ultrastrong and deep strong coupling regimes, where the atom-cavity coupling rat…
Corner space renormalization method for driven-dissipative 2D correlated systems
S. Finazzi, A. Le Boité, F. Storme +2
We present a theoretical method to study driven-dissipative correlated systems on lattices with two spatial dimensions (2D). The steady-state density-matrix of the lattice is obtai…
Bose-Hubbard Model: Relation Between Driven-Dissipative Steady-States and Equilibrium Quantum Phases
Alexandre Le Boité, Giuliano Orso, Cristiano Ciuti
We present analytical solutions for the mean-field master equation of the driven-dissipative Bose-Hubbard model for cavity photons, in the limit of both weak pumping and weak dissi…
Steady-state phases and tunneling-induced instabilities in the driven-dissipative Bose-Hubbard model
Alexandre Le Boité, Giuliano Orso, Cristiano Ciuti
We determine the steady-state phases of a driven-dissipative Bose-Hubbard model, describing, e.g., an array of coherently pumped nonlinear cavities with a finite photon lifetime. W…
