Modeling and Control of the LKB Photon-Box: 1 Quantum Non-Demolition (QND) Measurement

From our measured dust polarization angles, we infer a magnetic field orientation projected onto the plane of the sky (POS) that is remarkably ordered over the full extent of the

The second aspect of the AB effect exhibits that the force concept gradually fades away in Quantum Mechanics2. Instead of forces,

3 shows the distribution of the normal component of the magnetic field strength created by the planar flux inductor (dash-dotted line), eddy currents (dashed line), and the

Process tomography of field damping and measurement of Fock state lifetimes by quantum non-demolition photon counting in a cavity... Curie, 24 rue Lhomond, F-75231 Paris Cedex

We initialize the field in |0〉 by first absorbing thermal photons with ∼10 atoms prepared in g and tuned to resonance with the cavity mode (residual photon number ∼

The telegraphic signals 29 obtained by detecting a stream of atoms reveal the photon number evolution, with quantum jumps between n = 0 and 1 as the field randomly exchanges

The Rabi frequency, Ω 0 /2π = 49.8 kHz, the probability p 1 = 0.09 for having initially one photon in C and the precise position of the exciting laser beams inside the cavity

We also note that given a well-known down- conversion process, the nonlocal phase of the daughter photon pair encodes the phase of the pump pulse and is invariant under local
