Abstract

A scheme for the generation of the pure fock states via the two photon resonant interaction and single photon resonant interaction of two level atoms and single mode cavity field is presented.In this case,we have performed a state selective measurement on the atom.

A scheme for generating two-photon and three-photon states of a cavity field using resonant single atoms

Shi-Biao Zheng

We propose a scheme for generating two-photon states for a cavity field. In the scheme the cavity initially contains a small coherent or thermal field. Then a resonant two-level atom is sent through the cavity. After an appropriate interaction time the atom is state-selectively measured, which may collapse the cavity field onto a two-photon state. A three-photon state of rather high fidelity can also be generated with a single atom.

Photon-number-state generation with a single two-level atom in a cavity: a proposal

P. Domokos, M. Brune, J. M. Raimond +2 more

A single two-level atom can be used to prepare an arbitrary photon number state (Fock state) in a high Q cavity . The atom undergoes a controlled succession of interactions with two cavity modes. One of them contains a coherent field. The atom transfers photons one by one from this field to the initially empty second mode. The scheme can be extended to prepare a quantum superposition of the vacuum with a Fock state, a highly non-classical situation. We discuss the feasibility of the experiment with our present Rydberg-atom cavity QED set-up.

Generation of SU(2) Coherent States for a Cavity Mode and a Collective Atomic Mode

Zheng Shi-Biao

We propose a scheme for generation of SU(2) coherent states for an atomic ensemble and a cavity mode. In the scheme a collection of two-level atoms resonantly interact with a single-mode quantized field. Under certain conditions, the system can evolve from a Fock state to a highly entangled SU(2) coherent state. The operation speed increases as the number of atoms increases, which is important in view of decoherence.

Controlled hole burning in Fock space via resonant interaction

Ardiley Torres Avelar, B. Baseia

We propose an alternative and simple method to create states of the quantized radiation field with controlled holes in their photon-number distribution. The scheme relies on resonant interaction of a cavity field with two-level Rydberg atoms plus selective atomic detection.
