Proposal to produce long-lived mesoscopic superpositions through an atom–driven field interaction

Abstract

We present a proposal for the production of longer-lived mesoscopic superpositions which relies on two requirements: parametric amplification and a squeezed vacuum reservoir for cavity-field states. Our proposal involves the interaction of a two-level atom with a cavity field which is simultaneously subjected to amplification processes.

Preparation and control of a cavity-field state through an atom–driven-field interaction: Towards long-lived mesoscopic states

Celso J. Villas-Bôas, Fernando Rogério de Paula, Roberto M. Serra +1 more

The preparation of mesoscopic states of radiation and matter fields through atom-field interactions has been achieved in recent years and employed for a range of striking applications in quantum optics. Here we present a technique for the preparation and control of a cavity mode which, in addition to interacting with a two-level atom, is simultaneously submitted to linear and parametric amplification processes. The role of the amplification-controlling fields in the achievement of real mesoscopic states is to produce highly squeezed field states and, consequently, to increase both (i) the distance in phase space between the components of the prepared superpositions and (ii) the mean photon number of such superpositions. When the squeezed superposition states are submitted to the action of similarly squeezed reservoirs, we demonstrate that under specific conditions the decoherence time of the states becomes independent of both the distance in phase space between their components and their mean photon number. An explanation is presented to support this remarkable result, together with a discussion of the experimental implementation of our proposal. We also show how to produce number states with fidelities higher than those derived as circular states.

Superposition and entanglement of mesoscopic squeezed vacuum states in cavity QED

Changyong Chen, Mang Feng, Kelin Gao

We propose a scheme to generate superposition and entanglement between the mesoscopic squeezed vacuum states by considering the two-photon interaction of $N$ two-level atoms in a cavity with high quality factor, assisted by a strong driving field. By virtue of specific choices of the cavity detuning, a number of multiparty entangled states can be prepared, including the entanglement between the atomic and the squeezed vacuum cavity states and between the squeezed vacuum states and the coherent states of the cavities. We also present how to prepare entangled states and ``Schr\"odinger cats'' states regarding the squeezed vacuum states of the cavity modes. The possible extension and application of our scheme are discussed. Our scheme is close to the reach with current cavity QED techniques.

Non-classical state stabilization in a cavity by reservoir engineering

Alain Sarlette, J. M. Raimond, Pierre Rouchon

We propose an engineered reservoir inducing the relaxation of a cavity field towards non-classical states. It is made up of two-level atoms crossing the cavity one at a time. Each atom-cavity interaction is first dispersive, then resonant, then dispersive again. The reservoir pointer states are those produced by a fictitious Kerr Hamiltonian acting on a coherent field. We thereby stabilize squeezed states and quantum superpositions of multiple coherent components in a cavity having a finite damping time. This robust method could be implemented in state-of-the-art experiments and lead to interesting insights into mesoscopic quantum state superpositions.

Scheme for efficient generation of mesoscopic field-state superposition in cavity QED

Carla Hermann-Avigliano, Nataly Cisternas, M. Brune +2 more

We present a simple scheme for the fast and efficient generation of quantum superpositions of two coherent fields with different classical amplitudes in a cavity. It relies on the simultaneous interaction of two two-level systems with the field. Their final detection with a high probability in the proper state projects the field onto the desired mesoscopic field state superposition. We show that the scheme is notably more efficient than those using a single atom. We discuss the method in the context of microwave cavity quantum electrodynamics, but it is also highly relevant for the thriving field of circuit QED. It may lead to interesting experimental studies of decoherence at the quantum-classical boundary.

Production of mesoscopic superpositions with ultracold atoms

H. T. Ng

We study mesoscopic superpositions of two component Bose-Einstein condensates. Atomic condensates, with long coherence times, are good systems in which to study such quantum phenomena. We show that the mesoscopic superposition states can be rapidly generated in which the atoms dispersively interact with the photon field in a cavity. We also discuss the production of compass states which are macroscopic quantum superposition states. The physical realization of mesoscopic states is important in studying decoherence and precision measurement.
