Physical Review A

Direct measurement of quasiprobability distributions in cavity QED

Raúl Juárez-Amaro, H. M. Moya-Cessa

Published Aug 6, 2003• 15 citations

Abstract

We show that the set of s-parametrized quasiprobability distribution functions corresponding to an electromagnetic field in a cavity subject to dissipation can be directly measured. Such distributions contain whole information of the quantum state, therefore making it possible to recover information after losses have occurred.

Measuring the quantum state of the electromagnetic field at finite temperature

Raúl Juárez-Amaro, H. M. Moya-Cessa

Abstract We show that it is possible to reconstruct the quantum state of light in a cavity subject to dissipation at finite temperature. By passing atoms through the cavity it is shown that the decay does not prevent the measurement of s-parametrized quasiprobability distributions. Because such distributions contain whole information about the initial quantized field, it is possible to recover its complete information.

Cavity Field Reconstruction at Finite Temperature

H. M. Moya-Cessa, A. Vidiella-Barranco, P. Tombesi +1 more

We present a scheme to reconstruct the quantum state of a field preparedinside a lossy cavity at finite temperature. Quantum coherences are normallydestroyed by the interaction with an environment, but we show that it ispossible to recover complete information about the initial state (beforeinteraction with its environment), making possible to reconstruct any$s$-parametrized quasiprobability distribution, in particular, the Wignerfunction.

Method for Direct Measurement of the Wigner Function in Cavity QED and Ion Traps

L. G. Lutterbach, L. Davidovich

We show that the Wigner function corresponding to an electromagnetic field in a cavity or a vibronic state of a trapped ion can be directly measured by means of a simple experimental procedure. The proposed method is insensitive to the relatively low detection efficiency in cavity QED experiments and yields a direct physical meaning to the Wigner distribution.

We present a scheme to reconstruct the quantum state of a field prepared inside a lossy cavity at finite temperature. Quantum coherences are normally destroyed by the interaction with an environment, but we show that it is possible to recover complete information about the initial state (before interaction with its environment), making possible to reconstruct any s-para-metrized quasiprobability distribution, in particular, the Wigner function.

SCHEME FOR DIRECT MEASURING QUASIPROBABILITY DISTRIBUTIONS OF N TRAPPED IONS IN THE DISPERSIVE REGIME

Wen‐Xing Yang, Xiao-Tao Xie, FANG-FANG LUO

In this letter, a procedure is proposed for reconstructing the motional quantum state of N trapped ions. Unlike other previous schemes, the present scheme works in the dispersive regime in the presence of dissipation. In our scheme, we show that it is possible to directly measure the quasiprobability distribution function corresponding to the motional coherent state in a trapped-ion system subjected to dissipation. We also provide an example of a motional Schrödinger cat state reconstruction to exemplify our procedure.

DIRECT MEASUREMENT OF PHASE AND QUASIPROBABILITY DISTRIBUTIONS OF STATES IN CAVITY QED

Arpita Ghosh, Pradip Das

We study the phase properties and quasiprobability distributions of different states produced in a cavity. The number-phase properties of the states are investigated using a methodology based on the Susskind–Glogower formalism. Also the Husimi Q-functions are obtained and illustrated graphically.
