Abstract

We examine the validity of the Kraus representation in the presence of initial correlations and show that it is assured only when a joint dynamics is locally unitary.

Claims other papers make about this one

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

  • A map Φ from n×n matrices to m×m matrices is linear if and only if it can be represented in an operator sum representation with left and right operation elements.

    “Theorem 1 A map Φ : M n ↦→ M m (where M n is the space of n × n matrices) is linear iff it can be represented as”

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.
