Measuring nonequilibrium retarded spin-spin Green's functions in an ion-trap based quantum simulator
Bryce T. Yoshimura, J. K. Freericks
Recent work proposed a variant on Ramsey interferometry for coupled spin- systems that directly measures the retarded spin-spin Green's function. We expand on that work by inv…
Bang-bang shortcut to adiabaticity in trapped ion quantum simulators
Shankar Balasubramanian, Shuyang Han, Bryce T. Yoshimura +1
We model the bang-bang optimization protocol as a shortcut to adiabaticity in the ground-state preparation of an ion-trap-based quantum simulator. Compared to a locally adiabatic e…
Creating thermal distributions from diabatic excitations in ion-trap-based quantum simulation
M. H. Lim, B. T. Yoshimura, J. K. Freericks
The goal of adiabatic ground-state preparation is to start a simple quantum system in its ground state and adiabatically evolve the Hamiltonian to a complex one, maintaining the gr…
Determining the ground-state probability of a quantum simulation with product-state measurements
Bryce Yoshimura, J. K. Freericks
One of the goals in quantum simulation is to adiabatically generate the ground state of a complicated Hamiltonian by starting with the ground state of a simple Hamiltonian and slow…
