Abstract

A scheme is presented for generating any anticorrelated state of a two-mode field. In the scheme a sequence of suitably prepared three-level V-type atoms are sent across a two-mode cavity initially in the vacuum state. The detection of all the atoms in the ground state collapses the two-mode field to the desired state.

An Alternative Scheme to Generate Arbitrary Anticorrelated States of a Two-Mode Field via Λ-type Atom Resonant Interaction with a Two-Mode Cavity Field

An alternative scheme is presented to generate arbitrary anticorrelated states of a two-mode field. In the scheme, a sequence of Λ-type three-level atoms are orderly sent across the cavity to interact with the cavity field initially in the two-mode vacuum state. The detection of all the atoms in the ground state collapses the two-mode field to the desired state. In this way, we can prepare the anticorrelated states of a two-mode field.

Generating Even-Photon State via Resonant Interaction Between Ladder-Type Three-Level Atoms with a Single-Mode Field

Zhong Zhi-Rong, Wan-Jun Su

A scheme is presented to generate even-photon state based on resonant interaction between ladder-type three-level atoms with a single-mode field. In the scheme, a sequence of suitably prepared ladder-type three-level atoms are orderly sent through a single-mode cavity initially in vacuum state. The detection of all the atoms in the ground states collapses the cavity to the desired state. The scheme is based on the resonant interaction of atoms with the cavity, and thus the required interaction time can be greatly shortened. This is important in view of decoherence.

Efficient Scheme for the Generation of Atomic Schrödinger Cat States in an Optical Cavity

Zheng Shi-Biao, Lin Li-Hua, Jiang Yun-kun

An efficient scheme is proposed for the generation of atomic Schrödinger cat states in an optical cavity. In the scheme N three-level atoms are loaded in the optical cavity. Raman coupling of two ground states is achieved via a laser field and the cavity mode. The cavity mode is always in the vacuum state and the atoms have no probability of being populated in the excited state. Thus, the scheme is insensitive to both the cavity decay and spontaneous emission.

Generation of Multi-atom Entangled States via the Raman Atom-Cavity-Field Interaction

Zheng Shi-Biao, Guo Guang-Can

A scheme is presented for preparing multi-atom entangled states based on the Raman atom-cavity-field interaction. After several degenerate Λ-type three-level atoms interact with an appropriately prepared single-mode cavity field through Raman coupling, a two-level atom, resonant with the cavity, is sent through the cavity and a Ramsey zone. The detection of the two-level atom leaves the Λ-type atoms in an entangled state.
