Quantum phase-gate implementation for trapped ions in thermal motion
Xu‐Bo Zou, K. Pahlke, Wolfgang M. Mathis · Physical Review A · 2002
We propose a scheme to implement a quantum controlled phase gate for trapped ions in thermal motion with one standing-wave laser pulse. Instead of applying the rotating-wave approximation, this scheme makes use of the counter-rotating terms of the operators. We also demonstrate that the same scheme can be used to generate maximally entangled states of N trapped ions by a single laser pulse.
