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…

Universal Hamiltonians for Exponentially Long Simulation
Thomas C. Bohdanowicz, Fernando G. S. L. Brandão
We construct a Hamiltonian whose dynamics simulate the dynamics of every other Hamiltonian up to exponentially long times in the system size. The Hamiltonian is time-independent, l…
