Non-linear magneto-optic and self polarization rotation by superposition of states
Non-linear magneto-optic self polarization rotation superposition of states Optics
2012/4/24
We report the observation of enhanced magneto-optic rotation as the coherent superposition of different hyperfine states is established in an atomic sample. The polarization rotation near the two phot...
Superemitters in Hybrid Photonic Systems: A Simple Lumping Rule for the Local Density of Optical States and its Break-Down at the Unitary Limit

2012/4/20
We theoretically investigate how the enhancement of the radiative decay rate of a spontaneous emitter provided by coupling to an optical antenna is modified when this "superemitter" is introduced into...

Abstract: We consider the problem of teleporting superposed coherent state using non-maximally entangled coherent state as quantum channel and study the effect of entanglement over quality of teleport...
Cross-Kerr nonlinearity between continuous-mode coherent states and single photons
Cross-Kerr nonlinearity continuous-mode coherent states single photons
2013/7/3
Weak cross-Kerr nonlinearities between single photons and coherent states are the basis for many applications in quantum-information processing. These nonlinearities have so far mainly been discussed ...
We construct a class of coherent spin-network states that capture proprieties of curved space-times of the Friedmann-Lamaˆıtre-Robertson-Walker type on which they are peaked.
Dynamic of rescattering-electron wave packets in strong and short-wavelength laser fields: Roles of Coulomb potential and excited states

2014/5/28
We investigate the high-order harmonic generation of atoms and molecules exposed in strong and shortwavelength (shorter than 800 nm) laser fields. Our simulations show that the electronic rescattering...

Repulsively-bound exciton-biexciton states optical lattices
2010/11/17
We show that the interplay between spin-changing collisions and quadratic Zeeman coupling
provides a novel mechanism for the formation of repulsively bound composites in high-spin fermions,which we i...

2010/11/9
Artificial molecules containing just one or two electrons provide a powerful platform for studies of orbital and spin quantum dynamics in nanoscale devices. A well-known example of these dynamics is t...

2010/10/21
We propose a practical physical system for creation of a stationary entanglement by dissipation without employing the environment engineering techniques. The system proposed is composed of two perfect...

2010/10/21
We discuss the creation of non-classical light from collective atomic states that are prepared in a ring-shaped lattice. These states are realized by exploiting the strong interaction between atoms in...

In this work we generate two-photon hybrid entangled states (HES), where the polarization of one photon is entangled with the transverse spatial degree of freedom of the second photon. The photon pair...

We propose a high efficiency tomographic scheme to reconstruct an unknown quantum state of the qubits by using a series of quantum nondemolition (QND) measurements. The proposed QND measurements of th...

We introduce a criterion to exclude full separability of quantum states. We present numerical evidence that the criterion is necessary and sufficient for the class of GHZ diagonal three-qubit states a...
Entanglement and nonclassicality for multi-mode radiation field states
Entanglement nonclassicality multi-mode radiation field states
2010/10/21
Nonclassicality in the sense of quantum optics is a prerequisite for entanglement in multi-mode
radiation states. In this work we bring out the possibilities of passing from the former to the
latter...
