Ground-state cooling enabled by critical coupling and dark entangled states
Cristian L. Cortes, Matthew Otten, Stephen K. Gray
We analyze the cooling of a mechanical resonator coupled to an ensemble of interacting two-level systems via an open quantum systems approach. Using an exact analytical result, we…
Noise-Resilient Quantum Dynamics Using Symmetry-Preserving Ansatzes
Matthew Otten, Cristian L. Cortes, Stephen K. Gray
We describe and demonstrate a method for the computation of quantum dynamics on small, noisy universal quantum computers. This method relies on the idea of `restarting' the dynamic…
Cooling a Mechanical Resonator with a Nitrogen-Vacancy Center Ensemble Using a Room Temperature Excited State Spin-Strain Interaction
E. R. MacQuarrie, M. Otten, S. K. Gray +1
We propose a protocol to dissipatively cool a room temperature mechanical resonator using a nitrogen-vacancy (NV) center ensemble. The spin ensemble is coupled to the resonator thr…
