Optical entanglement of co-propagating modes
Webvestigated in various fields of optical and atomic physics [1–3]. Many interesting properties and appli-cations based on EIT media are predicted and dem-onstrated, such as slow-light propagation [4,5] and enhanced giant Kerr nonlinearity [6,7]. In the begin-ning, the storage and retrieval of optical information WebFeb 18, 2024 · Here, we demonstrate a key step towards this vision, and generate entanglement between two propagating optical modes, by coupling them to the same, cryogenic mechanical system. The entanglement persists at room temperature, where we verify the inseparability of the bipartite state and fully characterize its logarithmic …

WebOptical entanglement is a key requirement for many quantum communication protocols. Conventionally, entanglement is formed between two distinct beams, with the quantum correlation measurements being performed at separate locations. WebAn optical system made of cylindrical lenses imparts a π/2 phase shift on one of the modes. Entanglement between 45 rotated spatial modes is analyzed using a QD set to a cor- rect …
WebJul 13, 2015 · This achievement opens the door to the microscopic characterization of strongly entangled many-body systems as well as to future uses of optical lattices in quantum information protocols. The demonstration of Bloch and co-workers is based on a cloud of rubidium-87 atoms confined in a two-dimensional optical lattice of 9 × 9 sites.

Their transverse profile inside the bulk medium is well-approximated by Gaussian beams, yet featuring spot diameters with significantly different sizes, dictated by a …
WebApr 10, 2024 · There are four ingoing modes (three arriving at the black-hole horizon and one at the white-hole horizon) and four outgoing modes. There are two real, propagating interior modes (int modes) between horizons; the other two modes within this region are evanescent (i.e., they have a complex wave number). Reuse & Permissions WebThe first protocol uses coherent states in a superposition as propagating modes in our entanglement swapping setup, whereas the second, more complicated, protocol uses superposed cat states. We model photonic losses by applying a beam-splitter of transmission T to our propagating continuous variable modes, along with an input …
