Hyperentanglement 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 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 کاملZeno effect in parametric down-conversion.
The Zeno effect refers to the inhibition of the isolated temporal evolution of a dynamical system when the observation of such evolution is attempted [1]. This observation is usually described by frequent measurements on the system performed in order to discover whether the initial state has changed or not. In the limit of very frequent measurements, continuous observation, or arbitrary high re...
متن کاملEntanglement in cascaded-crystal parametric down-conversion.
We use spontaneous parametric down-conversion in a cascade of crystals, driven by a single monochromatic cw pump laser, to study the interference of entangled photon pairs. By changing the distance between the crystals, the observed quantum interference pattern varies continuously from that associated with a longer single crystal to that associated with independent emissions from two distinct c...
