Marcin Zwierz, Carlos A. Perez-Delgado, Pieter Kok
TL;DR
This paper aimed to analyze the optimality of the Heisenberg limit in continuous-variable quantum metrology but was withdrawn due to a critical flaw in its proof.
Contribution
The paper intended to establish the Heisenberg limit's optimality in quantum metrology but was retracted because of a fundamental error.
Findings
Paper was withdrawn due to a fatal flaw in the proof.
No valid results or conclusions are presented.
Focus was on the theoretical limits of quantum measurement accuracy.
Abstract
This paper has been withdrawn by the authors due to a fatal flaw in the central proof.
