Quantum Phase Gate Operation Based on Nonlinear Optics: Full Quantum Analysis
C. Ottaviani, S. Rebic, D. Vitali +1
We present a full quantum treatment of a five-level atomic system coupled to two quantum and two classical light fields. The two quantum fields undergo a cross-phase modulation ind…
Continuous variable encoding by ponderomotive interaction
Stefano Pirandola, Stefano Mancini, David Vitali +1
Recently it has been proposed to construct quantum error-correcting codes that embed a finite-dimensional Hilbert space in the infinite-dimensional Hilbert space of a system descri…
Coherently-assisted incoherent population transfer in a five-level system
S. Rebic, D. Vitali, C. Ottaviani +1
A novel effect of population transfer in a five-level system is analyzed. This population transfer effect is found to be a version of a Raman process, which is facilitated and assi…
A Proposal for an Optical Implementation of an Universal Quantum Phase Gate
S. Rebic, D. Vitali, C. Ottaviani +4
Large optical nonlinearities occurring in a coherently prepared atomic system are shown to produce phase shifts of order . Such an effect may be observed in ultracold rubidium a…
Quantum dynamics in single spin measurement
Stefano Mancini, David Vitali, Hector Moya-Cessa
We study the quantum dynamics of a model for the single-spin measurement in magnetic-resonance force microscopy. We consider an oscillating driven cantilever coupled with the magne…
Light reflection upon a movable mirror as a paradigm for continuous variable teleportation network
Stefano Pirandola, Stefano Mancini, David Vitali +1
We present an optomechanical system as a paradigm of three-mode teleportation network. Quantum state transfer among optical and vibrational modes becomes possible by exploiting cor…
