Abstract

An efficient method of quantum state engineering based on discrete superpositions of coherent states is presented. A systematic method is developed for obtaining optimized superpositions from the one-dimensional representation of the desired state. It is shown that superposition of even a small number of coherent states put along a straight line or on a circle in phase space can approximate nonclassical field states with a high degree of accuracy. An experimental scheme is proposed for generating equidistant coherent-state superpositions on a circle with arbitrary coefficients. \textcopyright{} 1996 The American Physical Society.

Quantum State Engineering Via Coherent-State Superpositions

József Janszky, Петер Адам, S. Szabó +1 more

The quantum interference between the two parts of the optical Schrodinger-cat state makes possible to construct a wide class of quantum states via discrete superpositions of coherent states. Even a small number of coherent states can approximate the given quantum states at a high accuracy when the distance between the coherent states is optimized, e. g. nearly perfect Fock state can be constructed by discrete superpositions of n + 1 coherent states lying in the vicinity of the vacuum state.

Quantum State Engineering by Superpositions of Coherent States along a Straight Line in Cavity Quantum Electrodynamics

Zheng Shi-Biao

A scheme is proposed for generating the superpositions of several coherent states in a cavity field with dispersive cavity quantum electrodynamics (QED). In the scheme, a sequence of atoms interacts dispersively with the cavity field, connected with a microwave source, and is manipulated by classical fields, followed by state-selective measurements. In this way, the cavity field is collapsed onto a superposition of several coherent states along a straight line with controllable coefficients. This scheme provides the possibility for quantum state engineering via coherent-state superpositions in cavity QED for the first time.

Quantum state engineering via coherent-state superpositions in traveling optical fields

Emese Paari‐Molnar, Петер Адам, Gabor Mogyorosi +1 more

We propose two experimental schemes for producing coherent-state superpositions which approximate different nonclassical states conditionally in traveling optical fields. Although these setups are constructed of a small number of linear optical elements and homodyne measurements, they can be used to generate various photon number superpositions in which the number of constituent states can be higher than the number of measurements in the schemes. We determine numerically the parameters to achieve maximal fidelity of the preparation for a large variety of nonclassical states, such as amplitude squeezed states, binomial states, squeezed cat states, and various photon number superpositions. The proposed setups can generate these states with high fidelities and with success probabilities that can be sufficient for practical applications.

A representation of a Fock state \ensuremath{\Vert}n〉 is given by a superposition of n+1 coherent states. These discrete coherent-state superpositions provide experimental possibilities for generating an arbitrary quantum state of a single-mode electromagnetic field.

Quantum-state engineering of a trapped ion by coherent-state superpositions

H. M. Moya-Cessa, Sascha Wallentowitz, W. Vogel

We propose a procedure that allows one to create arbitrary, discrete superpositions of coherent states of the quantized center-of-mass motion of a trapped ion along a line in phase space. In view of the overcompleteness of the coherent states, such a method can be used for the engineering of motional quantum states.

One dimensional representations in quantum optics

József Janszky

As a generalization of the optical Schroedinger cats discrete and continuous sets of coherent states are considered on a circle and on a straight line in the a-plane. The interference fringes between the coherent states of the Schroedinger cats form the characteristic pattern of the nonclassical states in Wigner function picture. Continuos superpositions of coherent states on these one-dimensional manifolds can serve as an orthonormal basis for representation of any states.
