Thermometry of Trapped Ions Based on Bichromatic Driving
Xie-Qian Li, Yi Tao, Ting Chen +4
Accurate thermometry of laser-cooled ions is crucial for the performance of the trapped-ions quantum computing platform. However, most existing methods face a computational exponen…
Phonon Number Measurement Using Optimal Composite Pulses
Xie-Qian Li, Chun-Wang Wu, Ping-Xing Chen
Measuring the phonon number of the laser-cooled ions is an indispensable step in evaluating whether an ion is in ground state. At present, commonly used methods in the experiments…
Accelerating relaxation through Liouvillian exceptional point
Yan-Li Zhou, Xiao-Die Yu, Chun-Wang Wu +4
We investigate speeding up of relaxation of Markovian open quantum systems with the Liouvillian exceptional point (LEP), where the slowest decay mode degenerate with a faster decay…
Fast Laser Cooling Using Optimal Quantum Control
Xie-Qian Li, Shuo Zhang, Jie Zhang +3
Cooling down a trapped ion into its motional ground state is a central step for trapped ions based quantum information processing. State of the art cooling schemes often work under…
