Distilling angular momentum nonclassical states in trapped ions

Abstract

In the spirit of quantum nondemolition measurements, we show that by exploiting suitable vibronic couplings and repeatedly measuring the atomic population of a confined ion, it is possible to distill center-of-mass vibrational states with a well-defined square of angular momentum or, alternatively, angular momentum projection Schr\"odinger cat states.

In the spirit of quantum nondemolition measurement we show that repeatedly measuring the atomic state of a trapped ion subjected to suitable vibronic couplings it is possible to extract interesting nonclassical states. The possibility of generating angular momentum Schrödinger cat is demonstrated.

Quantum nondemolition measurements of vibrational populations in ionic traps

L. Davidovich, Miguel Orszag, Nicim Zagury

We discuss a simple implementation of a quantum nondemolition measurement of the vibronic state of a trapped ion. This scheme allows the production of Fock states associated to the center-of-mass motion and the determination of the population distribution of the trap levels, and is based on the vibronic level dependence of the frequency of Rabi oscillations between two internal states of the ion, induced by a resonant carrier field. The same scheme can be used to produce a Schr\"odinger-cat-like state after a single interaction between the trapped ion and the carrier pulse, followed by the detection of the ionic internal state. \textcopyright{} 1996 The American Physical Society.

Realization of Nonclassical States and Two-Mode Coupling in the Motion of Two Trapped Ions

Zheng Shi-Biao

We propose a scheme to generate various nonclassical vibrational states in the collective motion of two trapped ions, such as squeezed states, Schrödinger cat states, and SU(2) states. It is based on Raman-type excitations. Two-mode coupling between the center-of-mass and relative vibrational modes can also be realized.

Generation of nonclassical states of the center-of-mass motion of ions by dispersive coupling

J. C. Retamal, Nicim Zagury

We consider a dispersive effective coupling between the internal energy electronic levels of an ion in a trap with its own center-of-mass motion. By using a procedure similar to the Ramsey oscillatory method, a quantum nondemolition experiment of the center-of-mass vibration population number is proposed. A procedure to generate squeezed states and Schr\"odinger-cat-like states that are superpositions of squeezed states is also suggested.

Summary form only given.The recent progress in trapping and cooling of atoms allowed us to prepare and to measure various nonclassical states of atomic motion. These methods make use of the laser-assisted vibronic interaction of the trapped atom. The interaction Hamiltonian for the laser being resonant to the kth vibrational sideband.
