Phase states for a three-level atom interacting with quantum fields
A. B. Klimov, L. L. Sanchez-Soto, J. Delgado +1
We introduce phase operators associated with the algebra su(3), which is the appropriate tool to describe three-level systems. The rather unusual properties of this phase are cause…
Two-photon imaging and quantum holography
Gunnar Bjork, Jonas Soderholm, Luis L. Sanchez-Soto
It has been claimed that ``the use of entangled photons in an imaging system can exhibit effects that cannot be mimicked by any other two-photon source, whatever strength of the co…
Effective Hamiltonians in quantum optics: a systematic approach
A. B. Klimov, L. L. Sanchez-Soto, A. Navarro +1
We discuss a general and systematic method for obtaining effective Hamiltonians that describe different nonlinear optical processes. The method exploits the existence of a nonlinea…
A description of entanglement in terms of quantum phase
Luis L. Sanchez-Soto, Julian Delgado, Andrei B. Klimov +1
We explore the role played by the phase in an accurate description of the entanglement of bipartite systems. We first present an appropriate polar decomposition that leads to a tru…
