Theory of quantum frequency translation of light in optical fiber: application to interference of two photons of different color
quantum frequency translation light optical fiber photons Quantum Physics
2011/8/17
Abstract: We study quantum frequency translation and two-color photon interference enabled by the Bragg scattering four-wave mixing process in optical fiber. Using realistic model parameters, we compu...

2011/9/14
In Nature Photonics 5, 166 (2011), we reported on a planar dielectric antenna that achieved 96% efficiency in collecting the photons emitted by a single molecule. In that work the transition dipole mo...
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 ...

2013/7/3
The controlled-Z ( CZ) operations acting separately on pairs of qubits are commonly adopted in the schemes of generating graph states, the multipartite entangled states for the one-way quantum computi...

Coincident-Frequency Entangled Photons Homogenous Gravitational Field - A
2010/12/20
Assuming that the Principle of energy conservation holds for coincident-frequency entangled pho-tons propagating in a homogeneous gravitational field. It is argued that in this physical context,either...

2010/11/17
We show that the use of entangled photons having non-zero orbital angular momentum (OAM) increases the resolution and sensitivity of angular-displacement measurements performed using an interferomete...

Photon bremsstrahlung is studied for identifying elastic proton-proton interactions in the
CMS experiment at the LHC. In addition to measurement of the elastic pp cross section

2010/11/9
We present an experiment of nonclassical interference between a pure heralded single-photon state and a weak coherent state. Our experiment is the first to demonstrate that spectrally pure single phot...
Fock-state view of weak-value measurements and implementation with photons and atomic ensembles
Fock-state view weak-value measurements implementation photons atomic ensembles
2010/11/5
Weak measurements in combination with post-selection can give rise to a striking amplification effect (related to a large "weak value"). We show that this effect can be understood by viewing the initi...
