Motional-state analysis of a trapped ion by ultranarrowband composite pulses

M Mallweger, M Guevara-Bertsch, BT Torosov… - Physical Review A, 2024 - APS
In this work, we present a method for measuring the motional state of a two-level system
coupled to a harmonic oscillator. Our technique uses ultranarrowband composite pulses on …
