Remote Cooling of Spin-ensembles through a Spin-mechanical Hybrid Interface
arxiv(2024)
摘要
We present a protocol for the ground-state cooling of a tripartite hybrid
quantum system, in which a macroscopic oscillator acts as a mediator between a
single probe spin and a remote spin ensemble. In the presence of weak
dispersive coupling between the spins and the oscillator, cooling of the
oscillator and the ensemble spins can be achieved by exploiting the feedback
from frequent measurements of the single probe spin. We explore the parameter
regimes necessary to cool the ensemble, the oscillator, or both to their
thermal ground states. This novel cooling protocol shows that, even with only
weak dispersive coupling, energy transfer-like effects can be obtained by
simply manipulating the probe spin. These results not only contribute to the
development of a practical solution for cooling/polarizing large spin
ensembles, but also provide a relatively simple means of tuning the dynamics of
a hybrid system. The proposed cooling protocol thus has broader implications
for advancing various quantum technology applications, such as macroscopic
quantum state generation and remote sensing.
