On the dynamics of maximum extractable entanglement for open systems
E. Isasi, D. Mundarain, J. Stephany
In this work we study the dynamics of the maximum extractable entanglement for a system composed of two qubits interacting either with two independent thermal baths, a common therm…
Concurrence and negativity as distances
D. Mundarain, J. Stephany
In this report we consider the three dimensional subset of the space of states of two qubits that may be written in the so called standard form. For those states we show that diffe…
Total Quantum Zeno Effect beyond Zeno Time
D. Mundarain, M. Orszag, J. Stephany
In this work we show that is possible to obtain Total Quantum Zeno Effect in an unstable systems for times larger than the correlation time of the bath. The effect is observed for…
Decoherence Free Subspace and entanglement by interaction with a common squeezed bath
D. Mundarain, M. Orszag
In this work we find explicitly the decoherence free subspace (DFS) for a two two-level system in a common squeezed vacuum bath. We also find an orthogonal basis for the DFS compos…
Total Quantum Zeno effect and Intelligent States for a two level system in a squeezed bath
D. Mundarain, M. Orszag, J. Stephany
In this work we show that by frequent measurements of adequately chosen observables, a complete suppression of the decay in an exponentially decaying two level system interacting w…
Husimi's function and quantum interference in phase space
D. F. Mundarain, J. Stephany
We discuss a phase space description of the photon number distribution of non classical states which is based on Husimi's function and does not rely in the WKB approximation…
