High-fidelity dimer excitations using quantum hardware
Norhan M. Eassa, Joe Gibbs, Zoe Holmes +7
Many-body entangled quantum spin systems exhibit emergent phenomena such as topological quantum spin liquids with distinct excitation spectra accessed in inelastic neutron scatteri…
Enhancing the Expressivity of Variational Neural, and Hardware-Efficient Quantum States Through Orbital Rotations
Javier Robledo Moreno, Jeffrey Cohn, Dries Sels +1
Variational approaches, such as variational Monte Carlo (VMC) or the variational quantum eigensolver (VQE), are powerful techniques to tackle the ground-state many-electron problem…
A stochastic quantum Krylov protocol with double factorized Hamiltonians
Nicholas H. Stair, Cristian L. Cortes, Robert M. Parrish +2
We propose a class of randomized quantum Krylov diagonalization (rQKD) algorithms capable of solving the eigenstate estimation problem with modest quantum resource requirements. Co…
Quantum Filter Diagonalization with Double-Factorized Hamiltonians
Jeffrey Cohn, Mario Motta, Robert M. Parrish
We demonstrate a method that merges the quantum filter diagonalization (QFD) approach for hybrid quantum/classical solution of the time-independent electronic Schrödinger equation…
Bang-bang shortcut to adiabaticity in the Dicke model as realized in a Penning trap experiment
J. Cohn, A. Safavi-Naini, R. J. Lewis-Swan +7
We introduce a bang-bang shortcut to adiabaticity for the Dicke model, which we implement via a 2-D array of trapped ions in a Penning trap with a spin-dependent force detuned clos…
Verification of a many-ion simulator of the Dicke model through slow quenches across a phase transition
A. Safavi-Naini, R. J. Lewis-Swan, J. G. Bohnet +7
We use a self-assembled two-dimensional Coulomb crystal of ions in the presence of an external transverse field to engineer a simulator of the Dicke Hamiltonian, an iconi…
Exploring adiabatic quantum dynamics of the Dicke model in a trapped ion quantum simulator
A. Safavi-Naini, R. J. Lewis-Swan, J. G. Bohnet +7
We use a self-assembled two-dimensional Coulomb crystal of ions in the presence of an external transverse field to engineer a quantum simulator of the Dicke Hamiltonian.…
Spin and pseudospin towers of the Hubbard model on a bipartite lattice
J. Z. Boretsky, J. R. Cohn, J. K. Freericks
In 1989, Lieb proved two theorems about the Hubbard model. One showed that the ground state of the attractive model was a spin singlet state (), was unique, and was positive d…
