Quantum Cryptography with Femtosecond Parametric down Conversion
We experimentally demonstrate a quantum cryptography system using two-photon entangled (EPR) states generated via the nonlinear process of spontaneous parametric down conversion pumped by a femtosecond laser. There are two major approaches in quantum cryptography which historically appeared almost simultaneously. One uses the quantum features of single photon states produced by signi cant atten...
متن کاملHyperentanglement in Parametric Down-Conversion
A theory of spontaneous parametric down-conversion, which gives rise to a quantum state that is simultaneously entangled in three-dimensional wavevector and polarization, allows us to understand the unusual characteristics of fourth-order quantum interference in many experiments, including ultrafast parametric down-conversion, the speci c example illustrated in this paper. The comprehensive app...
متن کاملQuantum entanglement swapping with spontaneous parametric down conversion
Two remote parties that have never interacted each other can be entangled through entanglement swapping operation done by a third party. Currently existing entanglement swapping experiments are done probabilistically by post-selection, i.e., once a successful swapping is verified, the resultant entanglement is destructed. We propose a simple non-post-selection scheme to demonstrate the high qua...
متن کاملOptimal down-conversion in compressed DCT domain with minimal operations
A new down-conversion scheme in the DCT domain is presented, which can be used in decoders of DCT-compressed images and videos. The down-conversion in the transform domain generally requires lower computational complexity than the spatial domain down-conversion. The proposed method also requires computational complexity comparable to other DCT domain techniques, and it is optimal in MSE sense, ...
متن کاملSimple and efficient quantum key distribution with parametric down-conversion.
We propose an efficient quantum key distribution protocol based on the photon-pair generation from parametric down-conversion (PDC). It uses the same experimental setup as the conventional protocol, but a refined data analysis enables detection of photon-number splitting attacks by utilizing information from a built-in decoy state. Assuming the use of practical detectors, we analyze the uncondi...
