Quantum Fluctuation Relations and the shortcut to adiabaticity with the trapped ion

Shuoming An

The Quantum fluctuation relations is regarded as the more accurate version of the second law of thermodynamics in the quantum regime. To test the quantum Jarzynski equality, the two points measurement of the quantum work is required. We utilize the phonon projective measurement to realize the directive measurement of quantum work and test the quantum Jarzynski equality with the trapped ion. When realizing the phonon projective measurement, the shortcut to adiabaticity (STA) for the two level system is applied. The STA will reduce the long duration required by the adiabatic process to arbitrarily short one. Later different STA protocols for the motional states are realized and compared. Among all different protocols, the counter-diabatic driving protocol stands out for its robustness without more payment of work.
