Abstract
We propose speeding up a single ion heat pump based on a tapered ion trap. If a trapped ion is excited in an oscillatory motion axially the radial degrees of freedom are cyclically expanded and compressed such that heat can be pumped between two reservoirs coupled to the ion at the turning points of oscillation. Through the use of invariant-based inverse engineering we can speed up the process without sacrificing the efficiency of each heat pump cycle. This additional control can be supplied with additional control electrodes or it can be encoded into the geometry of the radial trapping electrodes. We present a novel insight into how speed up can be achieved through the use of inverted harmonic potentials and verify the stability of such trapping conditions.
Highlights
Trapped ions are an established platform for realizing high-fidelity quantum information processing [1, 2], quantum simulation [3, 4], and precision metrology experiments [5, 6]
In this paper we study the reverse process, a single ion heat pump, and how this process can be sped up through the shortcut to adiabaticity technique involving the use of invariant-based inverse engineering [9, 10]
As in the single ion heat engine, the ion is confined in a harmonic potential and the motional radial degrees of freedom serve as the working agent, where we consider temperature only in the radial directions
