![]() ![]() It was found that VAT was a faster transport mechanism than DAT. Dephasing assisted transport (DAT, modelled using a broadband noise source), and vibration assisted transport (VAT, modelled as a structured noisy environment with a Lorentzian centred on the dressed state energy splitting) were compared. Low frequency perturbations, below the dressed state splitting of the system, were found to induce transport using sub-resonance transfer paths. Transport through the system was also found to be strongly dependent on the frequency components of the applied perturbation. Progress made during the past four decades in techniques for producing and controlling cold matter gave rise to the experimental manipulation of quantum. An optimum noise power for efficient transport in a linear network was observed and in addition, the theoretically predicted localisation, environmental noise assisted quantum transport (ENAQT) and Zeno-like regimes were identified. The effect of a noisy environment was modelled by a noisy pure dephasing classical field that perturbed the site energies. A current challenge is to preserve the coherence of the Rydberg spin wave during the operation of the switch, which would enable, for example. Aspects of this transport process were simulated experimentally using a three-site system composed of RF coupled magnetic sub-states of the F=1 state of rubidium 87. We consider an all-optical photon switch in an atomic gas which is gated via a so-called Rydberg spin wave, i.e., a single Rydberg excitation that is coherently shared by the whole ensemble. ![]() Available under License All rights reserved.Ī strong interplay between quantum coherence and a noisy protein environment was used to explain the high efficiency of exciton transport through the photosynthetic Fenna-Matthews-Olson (FMO) complex. ![]()
