Fluorescence interferometry
G. S. Paraoanu
We describe an interferometer based on fluorescent emission of radiation of two qubits in quasi-one-dimensional modes. Such a system can be readily realized with dipole emitters ne…
Running-phase state in a Josephson washboard potential
G. S. Paraoanu
We investigate the dynamics of the phase variable of an ideal underdamped Josephson junction in switching current experiments. These experiments have provided the first evidence fo…
Selection of Squeezed States via Decoherence
Gh. -S. Paraoanu
In the framework of Lindblad theory for open quantum systems, we calculate the entropy of a damped quantum harmonic oscillator which is initially in a quasi-free state. The maximal…
Persistent currents in a circular array of Bose-Einstein condensates
Gh. -S. Paraoanu
A ring-shaped array of Bose-Einstein condensed atomic gases can display circular currents if the relative phase of neighboring condensates becomes locked to certain values. It is s…
Josephson effect in superfluid atomic Fermi-gases
Gh. -S. Paraoanu, M. Rodriguez, P. Torma
We consider an analog of the internal Josephson effect in superfluid atomic Fermi-gases. Four different hyperfine states of the atoms are assumed to be trapped and to form two supe…
Fidelity for Multimode Thermal Squeezed States
Gh. -S. Paraoanu, H. Scutaru
In the theory of quantum transmission of information the concept of fidelity plays a fundamental role. An important class of channels, which can be experimentally realized in quant…
