Thermalization time bounds for Pauli stabilizer Hamiltonians
Kristan Temme
We prove a general lower bound to the spectral gap of the Davies generator for Hamiltonians that can be written as the sum of commuting Pauli operators. These Hamiltonians, defined…

A note on the runtime of a faulty Hamiltonian oracle
Kristan Temme
In these notes we show that it is impossible to obtain a quantum speedup for a faulty Hamiltonian oracle. The effect of dephasing noise to this continuous time oracle model has fir…

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…
