Suppression of effective noise in Hamiltonian simulations
arXiv:1707.08258 · doi:10.1103/PhysRevA.96.052328
Abstract
Simulating high-weight Hamiltonians can convert local noise on the original Hamiltonian into undesirable nonlocal noise on the simulated Hamiltonian. Here we show how starting from two-local Hamiltonian in the presence of non-Markovian noise, a desired computation can be simulated as well as protected using fast pulses, while maintaining an energy gap against the errors created in the process.
