Collective decoherence of cold atoms coupled to a Bose-Einstein condensate
M. A. Cirone, G. De Chiara, G. M. Palma +1
We examine the time evolution of cold atoms (impurities) interacting with an environment consisting of a degenerate bosonic quantum gas. The impurity atoms differ from the environm…
Entanglement Induced by Tailored Environments
Markus A. Cirone, G. Massimo Palma
We analyze a system consisting of two spatially separated quantum objects, here modeled as two pseudo-spins, coupled with a mesoscopic environment modeled as a bosonic bath. We sho…
Microwave potentials and optimal control for robust quantum gates on an atom chip
Philipp Treutlein, Theodor W. Hänsch, Jakob Reichel +3
We propose a two-qubit collisional phase gate that can be implemented with available atom chip technology, and present a detailed theoretical analysis of its performance. The gate…
Theoretical analysis of the implementation of a quantum phase gate with neutral atoms on atom chips
E. Charron, M. A. Cirone, A. Negretti +2
We present a detailed, realistic analysis of the implementation of a proposal for a quantum phase gate based on atomic vibrational states, specializing it to neutral rubidium atoms…
A simple quantum gate with atom chips
M. A. Cirone, A. Negretti, T. Calarco +2
We present a simple scheme for implementing an atomic phase gate using two degrees of freedom for each atom and discuss its realization with cold rubidium atoms on atom chips. We i…
Entanglement correlations, Bell inequalities, and the concurrence
Markus A. Cirone
Probabilities of measurement outcomes of two-particle entangled states give a physically transparent interpretation of the concurrence and of the I-concurrence as entanglement meas…
