Abstract

We investigate quantum transport in binary tree structures and in hypercubes for the disordered Frenkel-exciton Hamiltonian under pure dephasing noise. We compute the energy transport efficiency as a function of disorder and dephasing rates. We demonstrate that dephasing improves transport efficiency not only in the disordered case, but also in the ordered one. The maximal transport efficiency is obtained when the dephasing timescale matches the hopping timescale, which represent new examples of the Goldilocks principle at the quantum scale. Remarkably, we find that in weak dephasing regimes, away from optimal levels of environmental fluctuations, the average effect of increasing disorder is to improve the transport efficiency until an optimal value for disorder is reached. Our results suggest that rational design of the site energies statistical distributions could lead to better performances in transport systems at nanoscale when their natural environments are far from the optimal dephasing regime.

  • Several investigations have studied the scalability of BosonSampling in imperfect conditions, including losses, partial distinguishability, and generic experimental errors.

    “Since then, several investigations have been performed to study the scalability in imperfect conditions, such as in the presence of losses [570-573], partial distinguishability [574,575] and generic experimental errors [571,[576][577][578]”

    The Abstract and Results discuss quantum transport in binary trees and hypercubes, including losses, disorder, and dephasing—not the scalability of BosonSampling. Searches for BosonSampling, partial distinguishability, and generic experimental errors found no passage addressing the attributed claim. Page numbers were not available in our copy.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
