Quantum Gibbs Samplers: the commuting case
Michael J. Kastoryano, Fernando G. S. L. Brandao
We analyze the problem of preparing quantum Gibbs states of lattice spin Hamiltonians with local and commuting terms on a quantum computer and in nature. Our central result is an e…
Cellular-automaton decoders for topological quantum memories
Michael Herold, Earl T. Campbell, Jens Eisert +1
We introduce a new framework for constructing topological quantum memories, by recasting error recovery as a dynamical process on a field generating cellular automaton. We envisage…
Hypercontractivity of quasi-free quantum semigroups
Kristan Temme, Fernando Pastawski, Michael J. Kastoryano
Hypercontractivity of a quantum dynamical semigroup has strong implications for its convergence behavior and entropy decay rate. A logarithmic Sobolev inequality and the correspond…
