Abstract

An unknown quantum state \ensuremath{\Vert}\ensuremath{\varphi}〉 can be disassembled into, then later reconstructed from, purely classical information and purely nonclassical Einstein-Podolsky-Rosen (EPR) correlations. To do so the sender, ``Alice,'' and the receiver, ``Bob,'' must prearrange the sharing of an EPR-correlated pair of particles. Alice makes a joint measurement on her EPR particle and the unknown quantum system, and sends Bob the classical result of this measurement. Knowing this, Bob can convert the state of his EPR particle into an exact replica of the unknown state \ensuremath{\Vert}\ensuremath{\varphi}〉 which Alice destroyed.

  • The paper relies on this without support.

    If Alice knows beforehand that the unknown state belongs to a given orthonormal set, she can make a measurement whose result will allow her to make an accurate copy.

    “Only if Alice knows before- hand that ~qb) belongs to a given orthonormal set can she make a measurement whose result will allow her to make an accurate copy of [P).”
  • The paper relies on this without support.

    If the possibilities for the unknown state include two or more nonorthogonal states, then no measurement will yield sufficient information to prepare a perfectly accurate copy.

    “Conversely, if the possibilities for ~P) include two or more nonorthogonal states, then no measurement will yield sufhcient information to prepare a perfectly accurate copy.”
  • The paper relies on this without support.

    In general, there is no way to learn the state vector of an unknown quantum system.

    “Knowing the state vector ]P) itself would be sufficient information, but in general there is no way to learn it.”

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.

A language model drew the claims from the paper on 2026-10-11, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-11 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

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.
