N ov 2 00 8 Nonclassical Correlation of Polarisation Entangled Photons in a Biexciton - Exciton Cascade
نویسنده
چکیده
We develop a theoretical model to study the Intensity-Intensity correlation of polarisation entangled photons emitted in a biexciton-exciton cascade. We calculate the degree of correlation and show how polarisation correlations are affected by the presence of dephasing and energy level splitting of the excitonic states. Our theoretical calculations are in agreement with the recent observation of polarisation dependent Intensity-Intensity correlations from a single semiconductor quantum dot [R. M. Stevenson et. al. Nature 439, 179 (2006)] . Our model can be extended to study polarisation entangled photon emission in coupled quantum dot systems.

متن کاملCoherent generation of time-bin entangled photon pairs using the biexciton cascade and cavity-assisted piecewise adiabatic passage
We present a scheme to realize a deterministic solid-state source of time-bin entangled photon pairs using cavity-assisted piecewise adiabatic passage in a single quantum dot. The quantum dot is embedded inside a semiconductor microcavity, and the interaction of a coherent superposition of two temporally separated input pulses and the cavity mode leads to a piecewise adiabatic passage, which pr...
متن کاملCavity-assisted fast generation of entangled photon pairs through the biexciton-exciton cascade
We present a scheme for the fast cavity-assisted generation of entangled photon pairs from a single quantum dot coupled to a planar photonic crystal that support two orthogonally polarized cavity modes. We discuss “within generation” and “across generation” of entangled photons when both the biexciton to exciton, and the exciton to ground-state transitions, are coupled through cavity modes. In ...

متن کاملPhonon-assisted decoherence in the production of polarization-entangled photons in a single semiconductor quantum dot.
We theoretically investigate the production of polarization-entangled photons through the biexciton cascade decay in a single semiconductor quantum dot. In the intermediate state the entanglement is encoded in the polarizations of the first emitted photon and the exciton, where the exciton state can be effectively "measured" by the solid-state environment through the formation of a lattice dist...
