Phase Sensitivity of a Mach-Zehnder Interferometer
Luca Pezze', Augusto Smerzi
The best performance of a Mach-Zehnder interferometer is achieved with the input state |N_T/2 + 1>|N_T/2-1 > + |N_T/2 - 1>|N_T/2+1>, being N_T the total number of atoms/photons. Th…
Realization of a Decoherence-free, Optimally Distinguishable Mesoscopic Quantum Superposition
Francesco De Martini, Fabio Sciarrino, Veronica Secondi
We report the realization of an entangled quantum superposition of M=12 photons by a high gain, quantum-injected optical parametric amplification. The system is found so highly res…
Separating the classical and quantum information via quantum cloning
M. Ricci, F. Sciarrino, N. J. Cerf +3
An application of quantum cloning to optimally interface a quantum system with a classical observer is presented, in particular we describe a procedure to perform a minimal disturb…
Phase space contraction and quantum operations
Ignacio Garcia-Mata, Marcos Saraceno, Maria Elena Spina +1
We give a criterion to differentiate between dissipative and diffusive quantum operations. It is based on the classical idea that dissipative processes contract volumes in phase sp…
Pseudopotential method for higher partial wave scattering
Zbigniew Idziaszek, Tommaso Calarco
We present a zero-range pseudopotential applicable for all partial wave interactions between neutral atoms. For p- and d-waves we derive effective pseudopotentials, which are usefu…
Canonical quantization of nonlinear many body systems
A. M. Scarfone
We study the quantization of a classical system of interacting particles obeying a recently proposed kinetic interaction principle (KIP) [G. Kaniadakis, Physica A {\bf 296}, 405 (2…
Effects of single-qubit quantum noise on entanglement purification
Giuliano Benenti, Sara Felloni, Giuliano Strini
We study the stability under quantum noise effects of the quantum privacy amplification protocol for the purification of entanglement in quantum cryptography. We assume that the E9…
Dissipative quantum chaos: transition from wave packet collapse to explosion
Gabriel G. Carlo, Giuliano Benenti, Dima L. Shepelyansky
Using the quantum trajectories approach we study the quantum dynamics of a dissipative chaotic system described by the Zaslavsky map. For strong dissipation the quantum wave functi…
On the observability of Bell's inequality violation in the optical Stern-Gerlach model
M. Tumminello, A. Vaglica, G. Vetri
Using the optical Stern-Gerlach model, we have recently shown that the non-local correlations between the internal variables of two atoms that successively interact with the field…
Image transfer through a chaotic channel by intensity correlations
M. Bondani, E. Puddu, A. Andreoni
The three-wave mixing processes in a second-order nonlinear medium can be used for imaging protocols, in which an object field is injected into the nonlinear medium together with a…
Quantum spatial correlations in high-gain parametric down-conversion measured by means of a CCD camera
O. Jedrkiewicz, E. Brambilla, M. Bache +3
We consider travelling-wave parametric down-conversion in the high-gain regime and present the experimental demonstration of the quantum character of the spatial fluctuations in th…
Experimental reconstruction of photon statistics without photon counting
M. Bondani, G. Zambra, A. Andreoni +5
Experimental reconstructions of photon number distributions of both continuous-wave and pulsed light beams are reported. Our scheme is based on on/off avalanche photodetection assi…
A model of deterministic detector with dynamical decoherence
Jae Weon Lee, Dmitri V. Averin, Giuliano Benenti +1
We discuss a deterministic model of detector coupled to a two-level system (a qubit). The detector is a quasi-classical object whose dynamics is described by the kicked rotator Ham…
