Abstract

A known positive operator-valued measure (POVM) describing a desired receiver of quantum light states is converted into a description of parts - including a prism, beam splitters and detectors - arranged to make a laboratory instrument. The conversion is made in two stages. The first is a transparent example of Neumark's theorem, in which a two-dimensional (non-projective) POVM is converted into a Hermitian operator on a space of three dimensions. The second uses a known factorization of the Hermitian operator into a product of simpler operators, each a conventional description of an optical component. If the components behave according to their conventional descriptions, the receiver behaves in accord with the given POVM.

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

  • Generalised measurements (POVMs) are useful when distinguishing between nonorthogonal states and can be implemented with N ports.

    “These are particularly useful when we need to distinguish between nonorthogonal states, and they can be implemented with N ports as well (Myers and Brandt 1997).”

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.
