Generation of Superpositions of Two-Mode Coherent States for the Motion of Two Trapped Ions

Zheng Zheng, Shi-Biao

Abstract

We propose a method for the generation of superpositions of two-mode coherent states for the center-of-mass and relative vibrational modes of two trapped ions. In the scheme the ions are driven by a single travelling-wave laser field tuned to the carrier. Then a measurement of the internal states collapses the vibrational modes to the entangled coherent state.

Preparation of coherent-state superpositions and measurement of the Wigner function for the motion of two trapped ions

Shi‐Biao Zheng

We propose a scheme for generating superpositions of coherent states for both the centre-of-mass and relative vibrational modes of two trapped ions. In the proposed scheme two trapped ions are driven by two laser beams dispersively tuned to the first lower- and upper-vibrational sideband transitions, respectively. Under certain conditions, the measurement of the internal states leaves one vibrational mode in a superposition of two coherent states. Entangled coherent states for these two vibrational modes can also be generated. The scheme can be used to measure the Wigner function of one vibrational mode given that the other mode is initially in the vacuum state.

Generation of Vibrational Entangled Coherent States of Two Trapped Ions

Li-Hua Lin, Yun-Kun Jiang, Zhen‐Biao Yang +1 more

We propose a scheme for the generation of entangled coherent states for the center-of-mass and relative vibrational modes of two trapped ions. In the scheme the ions are simultaneously illuminated by a single standing-wave laser tuned to the carrier. The scheme allows the production of an entangled coherent states with a considerably high speed as long as a laser field of sufficiently high intensity is available.

Generation of Multi-mode Entangled Coherent States for N Trapped Ions in Strong-Excitation Regime

Zheng Shi-Biao

We propose a scheme to generate entangled coherent states for the vibrational modes of N trapped ions. In the scheme the first ion is sequentially excited by two travelling wave laser fields tuned to the ion transition. The scheme works in the strong-excitation regime, which is of experimental importance in view of decoherence.
