We propose, analyze and evaluate a technique for the joint measurement of time-frequency entanglement between two photons. In particular, we show that the frequency sum and time difference of two photons could be simultaneously measured through the sum-frequency generation process, without measuring the time or frequency of each individual photon. We demonstrate the usefulness of this technique by using it to design a time-frequency entanglement based continuous variable superdense coding and a…

Temporal shaping of entangled photons.
By performing spectral-phase manipulations, the second-order correlation function of the photons is tailor exactly like a coherent ultrashort pulse, enabling a direct observation of the two-photon wave function.
Experimental demonstration of high two-photon time-energy entanglement
We report on the experimental demonstration of high energy-time entanglement in two-photon states created in the process of spontaneous parametric down-conversion. We show that the classical variance
Distribution of time-energy entanglement over 100 km fiber using superconducting single-photon detectors.
This letter reports an experimental realization of distributing entangled photon pairs over 100 km of dispersion-shifted fiber and demonstrates that the distributed photon pairs can still be useful for quantum key distribution and other quantum communication tasks.
Spectroscopy by frequency-entangled photon pairs
Quantum spectroscopy was performed using the frequency-entangled broadband photon pairs generated by spontaneous parametric down-conversion. An absorptive sample was placed in front of the idler
Quantum illumination versus coherent-state target detection
Entanglement is arguably the key quantum-mechanical resource for improving the performance of communication, precision measurement and computing systems beyond their classical-physics limits. Yet
Enhanced Sensitivity of Photodetection via Quantum Illumination
It is shown that for photodetection, quantum illumination with m bits of entanglement can in principle increase the effective signal-to-noise ratio by a factor of 2m, an exponential improvement over unentangled illumination.
Generation of paired photons in a quantum separable state in Bragg reflection waveguides.
A novel approach for the generation of separable (quantum uncorrelated) photon pairs based on spontaneous parametric down-conversion in Bragg reflection waveguides composed of semiconductor AlGaN layers is proposed.
Violation of Bell Inequalities by Photons More Than 10 km Apart
A Franson-type test of Bell inequalities by photons 10.9 km apart is presented. Energy-time entangled photon pairs are measured using two-channel analyzers, leading to a violation of the inequalities
Monolithic source of photon pairs.
This work demonstrates efficient photon pair production in a semiconductor platform, gallium arsenide, for the first time that significant pair production has been demonstrated in a structure that can be electrically self-pumped and which can form the basis for passive optical circuitry, bringing us markedly closer to complete integration of quantum optical technologies.
Three-photon energy-time entanglement
Many-particle entangled states and entanglement between continuous properties are valuable resources for quantum information, but are notoriously difficult to generate. An experiment now entangles
