Experimental simulation of decoherence in photonics qudits
We experimentally perform the simulation of open quantum dynamics in single-qudit systems. Using a spatial light modulator as a dissipative optical device, we implement dissipative-dynamical maps onto qudits encoded in the transverse momentum of spontaneous parametric down-converted photon pairs. We show a well-controlled technique to prepare entangled qudits states as well as to implement diss...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Experimental observation of decoherence
In the 1980s, theoretical estimates showed that on macroscopic scales I decoherence occurs extremely rapidly, thus effectively precluding the observation of nonclassical I superposition states [21–23]. This immediately led to the question of how we may experimentally observe the continuous action of decoherence and thus the smooth transition from quantum to classical. Several challenges have to...
متن کاملGeneration of qudits and entangled qudits
We propose schemes for the generation of d-level quantum states qudits and quantum entangled states of N qudits by adopting the polarization degree of freedom of photons. Arbitrary qudits can be prepared by putting d−1 identical and independent photons each with a given polarization into a single spatial and temporal mode. Then, by using N such qudits, linear optics, and proper projection measu...
متن کاملSimulation of Decoherence in Fluctuation Electron Microscopy
Fluctuation Electron Microscopy (FEM) examines the scattering statistics from small volumes of thin amorphous materials to detect the presence of medium-range order (MRO) [1]. By now it has been thoroughly demonstrated, by both modeling and simulations, that FEM is extraordinarily sensitive to MRO, much more than high-resolution diffraction and high-resolution imaging. Experiments have confirme...
