Quantum and Classical Potts Criticality in Driven-Dissipative Bosonic Lattices
Jacopo Tosca, Zejian Li, Cristiano Ciuti
The emergence of equilibrium universality from intrinsically nonequilibrium dynamics is a fundamental open problem. Bose-Hubbard lattices realized in photonic and circuit-QED platf…
Variational Dynamics of Open Quantum Spin Systems in Phase Space
Jacopo Tosca, Zejian Li, Francesco Carnazza +1
We introduce a variational method for simulating the dynamics of interacting open quantum spin systems. The method is based on the spin phase-space representation and variationally…
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.…
Machine learning via relativity-inspired quantum dynamics
Zejian Li, Valentin Heyraud, Kaelan Donatella +2
We present a machine-learning scheme based on the relativistic dynamics of a quantum system, namely a quantum detector inside a cavity resonator. An equivalent analog model can be…
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…
Dissipative phase transition with driving-controlled spatial dimension and diffusive boundary conditions
Z. Li, F. Claude, T. Boulier +4
We investigate theoretically and experimentally a first-order dissipative phase transition, with diffusive boundary conditions and the ability to tune the spatial dimension of the…
Effective bath model for arrays of coupled non-Hermitian nanoresonators
Vincent Vinel, Zejian Li, Adrien Borne +4
Nanophotonics systems have recently been studied under the perspective of non-Hermitian physics. Given their potential for wavefront control, nonlinear optics and quantum optics, i…
Dissipation-induced antiferromagnetic-like frustration in coupled photonic resonators
Zejian Li, Ariane Soret, Cristiano Ciuti
We propose a photonic quantum simulator for anti-ferromagnetic spin systems based on reservoir engineering. We consider a scheme where quadratically driven dissipative Kerr cavitie…
Exact dynamics of the homogeneous two-qubit central spin model with the spin bath prepared in superpositions of symmetric Dicke states
Zejiang Li, Pei Yang, Wen-Long You +1
We obtain exact dynamics of a two-qubit central spin model (CSM) consisting of two interacting qubits homogeneously coupled to a spin bath via the -type coupling, with the bat…
