We propose and analyze a high-fidelity hot gate for generic spin-resonator systems which allows for coherent spin-spin coupling, in the presence of a thermally populated resonator mode.
Our scheme is non-perturbative, applies to a broad
class of physical systems, including for example spins coupled to circuit-QED
and surface acoustic wave resonators as well as nanomechanical oscillators, and
can be implemented readily with state-of-the-art experimental setups. We
provide and numerically verify simple expressions for the fidelity of creating
maximally entangled states under realistic conditions.
