Quantum Speed Limit of a Photon under Non-Markovian Dynamics

Open access
Xu, Zhen-Yu, Zhu, Shi-Qun·2014·Chinese Physics Letters

Abstract

Quantum speed limit (QSL) time under noise has drawn considerable attention in real quantum computational processes. Though non-Markovian noise is found to be able to accelerate quantum evolution for a damped Jaynes—Cummings model, in this work we show that non-Markovianity will slow down the quantum evolution of an experimentally controllable photon system. As an application, QSL time of a photon can be controlled by regulating the relevant environment parameter properly, which nearly reaches the currently available photonic experimental technology.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The expression for the quantum speed limit time and its behavior sensitively depend on the choice of the initial state.

    “However, it was also pointed out that the expression for τ QSL , and hence its behaviour sensitively depends on the choice of the initial state [152], which was confirmed by Zhu and Xu [153].”

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.
