Continuous quantum error correction for evolution under time-dependent Hamiltonians
J. Atalaya, S. Zhang, M. Y. Niu +4
We develop a protocol for continuous operation of a quantum error correcting code for protection of coherent evolution due to an encoded Hamiltonian against environmental errors, u…

Postponing the orthogonality catastrophe: efficient state preparation for electronic structure simulations on quantum devices
Norm M. Tubman, Carlos Mejuto-Zaera, Jeffrey M. Epstein +8
Despite significant work on resource estimation for quantum simulation of electronic systems, the challenge of preparing states with sufficient ground state support has so far been…
