Abstract

This paper proposes a quantum nondemolition measurement scheme for the photon number. The signal and probe optical waves interact via the optical Kerr effect. The optical phase of the probe wave is selected as the readout observable for the measurement of the photon number of the signal wave. The measurement accuracy \ensuremath{\Delta}n and the imposed phase noise \ensuremath{\Delta}\ensuremath{\varphi} of the signal wave satisfy Heisenberg's uncertainty principle with an equality sign, 〈(\ensuremath{\Delta}n${)}^{2}$〉〈(\ensuremath{\Delta}\ensuremath{\varphi}${)}^{2}$〉=(1/4). .AE

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?

  • Detection of the output ports of the Mach-Zehnder interferometer can reveal whether there was a photon in the signal beam without destroying the signal photon, a quantum non-demolition measurement.

    “Moreover, we obtain this information without destroying the signal photon.This is called a quantum non-demolition measurement (Imoto et al. 1985).”

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.
