Emulation of large-scale qubit registers with a phase-space approach
Christian de Correc, Denis Lacroix, Corentin Bertrand
A phase-space approach is used and benchmarked for the simulation of the continuous-time evolution of large registers of qubits. It is based on a statistical ensemble of independen…
Exploring fixed points and eigenstates of quantum systems with reinforcement learning
María Laura Olivera-Atencio, Jesús Casado-Pascual, Denis Lacroix
We introduce a reinforcement learning algorithm designed to identify the fixed points of a given quantum operation. The method iteratively constructs the unitary transformation tha…
Neutrino thermalization via randomization on a quantum processor
Oriel Kiss, Ivano Tavernelli, Francesco Tacchino +2
The dynamical evolution of neutrino flavor in supernovae can be modeled by an all-to-all spin Hamiltonian with random couplings. Simulating such two-local Hamiltonian dynamics rema…
Excited States from ADAPT-VQE convergence path in Many-Body Problems: application to nuclear pairing problem and molecule dissociation
Jing Zhang, Denis Lacroix
A quantum computing algorithm is proposed to obtain low-lying excited states in many-body interacting systems. The approximate eigenstates are obtained by using a quantum space dia…
Solving the Lipkin model using quantum computers with two qubits only with a hybrid quantum-classical technique based on the Generator Coordinate Method
Yann Beaujeault-Taudiere, Denis Lacroix
The possibility of using the generator coordinate method (GCM) using hybrid quantum-classical algorithms with reduced quantum resources is discussed. The task of preparing the basi…
Restoring symmetries in quantum computing using Classical Shadows
Edgar Andres Ruiz Guzman, Denis Lacroix
We introduce a method to enforce some symmetries starting from a trial wave-function prepared on quantum computers that might not respect these symmetries. The technique eliminates…
Efficient solution of the non-unitary time-dependent Schrodinger equation on a quantum computer with complex absorbing potential
Mariane Mangin-Brinet, Jing Zhang, Denis Lacroix +1
We explore the possibility of adding complex absorbing potential at the boundaries when solving the one-dimensional real-time Schrödinger evolution on a grid using a quantum comput…
