Cavity-state preparation using adiabatic transfer

Published May 25, 2005• 25 citations

Abstract

We show how to prepare a variety of cavity field states for multiple cavities. The state preparation technique used is related to the method of stimulated adiabatic Raman passage. The cavity modes are coupled by atoms, making it possible to transfer an arbitrary cavity field state from one cavity to another and also to prepare nontrivial cavity field states. In particular, we show how to prepare entangled states of two or more cavities, such as an Einstein-Podolsky-Rosen state and a $W$ state, as well as various entangled superpositions of coherent states in different cavities, including Schr\"odinger cat states. The theoretical considerations are supported by numerical simulations.

Preparation of W, GHZ, and two-qutrit states using bimodal cavities

Asoka Biswas, G. S. Agarwal

We show how one can prepare three-qubit entangled states like W-states, Greenberger-Horne-Zeilinger states as well as two-qutrit entangled states using the multi-atom two-mode entanglement. We propose a technique of preparing such a multi-particle entanglement using stimulated Raman adiabatic passage. We consider a collection of three-level atoms in Λ configuration simultaneously interacting with a resonant two-mode cavity for this purpose. Our approach permits a variety of multi-particle extensions.

Superposition of Fock states via adiabatic passage in a coupled four-level atom–cavity system

Gong Shang-Qing, Jin Shi-Qi, Ruxin Li +2 more

We have investigated the behaviour of an atom–cavity system via a stimulated Raman adiabatic passage technique in a four-level system, in which two dark states are present. We find, because of the coherent control field, that a superposition of Fock states can be prepared, even when the cavity is initially not in its vacuum state. This method provides a way to generate arbitrary quantum states of a cavity field.

Synthesis of arbitrary quantum states via adiabatic transfer of Zeeman coherence

A. S. Parkins, P. Marte, P. Zoller +1 more

A scheme for the preparation of general coherent superpositions of photon-number states is proposed. By strongly coupling an atom to a cavity field, atomic ground-state Zeeman coherence can be transferred by (coherent) adiabatic passage to the cavity mode and a general field state can be generated without atomic projection noise.

Preparation of superpositions of coherent states of a field via the Raman interaction

Shi-Biao Zheng, Guang‐Can Guo

A method is presented for generating superpositions of coherent states of a cavity field via the atom - cavity-field Raman interaction. After an atom has interacted with a cavity field, initially in a coherent state, it is detected through the Raman coupling. Then the cavity field collapses into a Schrödinger cat state.
