Dissipative preparation of entanglement in optical cavities
Dissipative preparation entanglement optical cavities
2010/11/8
We propose a novel scheme for the preparation of a maximally entangled state of two atoms in an optical cavity. Starting from an arbitrary initial state, a singlet state is prepared as the unique fixe...
Preparation of Schrödinger cat states with cold ions in a cavity beyond the Lamb-Dicke limit
Schrö dinger cat states cold ions the Lamb-Dicke limit

We investigate the dynamics of a cold trapped ion coupled to the quantized field inside a high-finesse cavity. We have used an approach for preparing the SC states of motion of ion. This approach, bas...
Combined quantum state preparation and laser cooling of a continuous beam of cold atoms

We propose and solve a simple but very general quantum model of an SU(2)spin interacting with a large external system with N states. The coupling is described by a random hamiltonian in a new general ...
Spin-squeezing and Dicke state preparation through single-photon heterodyne measurement
Dicke state single-photon heterodyne measurement

We investigate the collapse of a coherent superposition of two-level atoms induced by a single-photon heterodyne quantum non-demolition (QND) measurement, and show that such a measurement process lead...
Two-dimensional cluster-state preparation with linear ion traps

We present schemes to prepare two-dimensional cluster states [H. J. Briegel and R. Raussendorf, Phys. Rev. Lett. {\bf 86}, 910 (2001)] with atomic ions confined in a micro-structured linear ion trap a...

2010/4/12
We describe the preparation of atom-number states with strongly interacting bosons in one dimension, or spin-polarized fermions. The procedure is based on a combination of weakening and squeezing of t...
