Remote Spectral Measurement Using Entangled Photons
نویسندگان
چکیده
By utilizing the frequency anticorrelation of two-photon states produced via spontaneous parametric down conversion (SPDC), the working principle of a novel remote spectrometer is demonstrated. With the help of a local scanning monochromator, the spectral transmission function of an optical element (or atmosphere) at remote locations can be characterized for wide range of wavelengths with expected high resolution.

Stimulated Raman Spectroscopy with Entangled Light: Enhanced Resolution and Pathway Selection
We propose a novel femtosecond stimulated Raman spectroscopy (FSRS) technique that combines entangled photons with interference detection to select matter pathways and enhance the resolution. Following photoexcitation by an actinic pump, the measurement uses a pair of broad-band entangled photons; one (signal) interacts with the molecule and together with a third narrow-band pulse induces the R...
متن کاملTotal teleportation of a single-photon state
Recent demonstrations of teleportation have transferred quantum information encoded into either polarization or fieldquadrature degrees of freedom (DOFs), but an outstanding question is how to simultaneously teleport quantum information encoded into multiple DOFs. We describe how the transverse-spatial, spectral and polarization states of a single photon can be simultaneously teleported using a...
متن کاملTowards a periodic deterministic source of arbitrary single-photon states
We present an experimentally feasible scheme to create single photons deterministically out of a non-deterministic spontaneous parametric downconversion source. We give an efficiency analysis of obtaining exactly one photon in the output. Furthermore, we experimentally demonstrate a way to control the purity of an output photon using a partial measurement of a polarization-entangled photon pair...

A polarization mode dispersion (PMD) measurement of a commercial telecommunication wavelength selective switch (WSS) using a quantum interferometric technique with polarization-entangled states is presented. Polarization-entangled photons with a broad spectral width covering the telecom band are produced using a chirped periodically poled nonlinear crystal. The first demonstration of a quantum ...
متن کاملExperimental Quantum Teleportation
Quantum teleportation-transmission and reconstruction of over arbitrary distances of the state of a quantum system is described experimentally. During this process, we take a photon; transfer its property (polarization) to another photon-even if the two photons are remote locations. An initial photon, which carries the polarization that is to be transferred, and one of a pair of entangled photo...
