Spectral Analysis of Product Formulas for Quantum Simulation
Changhao Yi, Elizabeth Crosson
We consider Hamiltonian simulation using the first order Lie-Trotter product formula under the assumption that the initial state has a high overlap with an energy eigenstate, or a…
De-Signing Hamiltonians for Quantum Adiabatic Optimization
Elizabeth Crosson, Tameem Albash, Itay Hen +1
Quantum fluctuations driven by non-stoquastic Hamiltonians have been conjectured to be an important and perhaps essential missing ingredient for achieving a quantum advantage with…
Rapid mixing of path integral Monte Carlo for 1D stoquastic Hamiltonians
Elizabeth Crosson, Aram W. Harrow
Path integral quantum Monte Carlo (PIMC) is a method for estimating thermal equilibrium properties of stoquastic quantum spin systems by sampling from a classical Gibbs distributio…
Good approximate quantum LDPC codes from spacetime circuit Hamiltonians
Thomas C. Bohdanowicz, Elizabeth Crosson, Chinmay Nirkhe +1
We study approximate quantum low-density parity-check (QLDPC) codes, which are approximate quantum error-correcting codes specified as the ground space of a frustration-free local…
