  • Uhlmann identified quantum fidelity as the proper generalization of wavefunction overlap to mixed states.

    “It was Uhlmann [62] who realised that the proper generalisation of the overlap of wavefunctions is given by the quantum fidelity,”
  • The quantum statistical distance, also called the Bures angle, is given by the arccosine of the square root of the quantum fidelity.

    “the quantum statistical distance, aka the Bures angle is given by L(ρ 1 , ρ 2 ) = arccos F(ρ 1 , ρ 2 ) ,(70)”
  • For ε = 0, the condition F(̺,̺(t)) = 0 is equivalent to Tr[̺(t)̺] = 0.

    “Notice, finally, that for ǫ = 0 we reobtain all the results that were given in [6], since in this case the condition (7) is equivalent to the condition Tr[ ̺ ( t ) ̺ ] = 0 that was employed there [8].”

  • In the TIM, when disorder strength is comparable with the interactions, the critical point disappears and is replaced by a Griffiths phase extending across a region of size proportional to the disorder strength.

    “Indeed, in the TIM when the disorder strength is comparable with the interactions, the critical point disappears and is replaced by a so called Griffiths phase [180], extending across a region of size proportional to the disorder strength.”

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.
