Information gain and measurement disturbance for quantum agents
2024 · arXiv (Cornell University)
The traditional formalism of quantum measurement (hereafter ``TQM'') describes processes where some properties of quantum states are extracted and stored as classical information. While TQM is a natural and appropriate description of how humans interact …

Comment on “Saturating quantum advantages in postselected metrology with the positive Kirkwood-Dirac distribution”
2024 · Physical Review A
In a recent paper [Das, Modak, and Bera, Phys. Rev. A 107, 042413 (2023)], Das et al. claim that Kirkwood-Dirac negativity is not required to achieve anomalous values of the quantum Fisher information encoded in …

Entanglement, loss, and quantumness: When balanced beam splitters are best
2024 · arXiv (Cornell University)
Quantum optics routinely uses beam splitters to generate entanglement, including in pioneering experiments conducted by Hanbury-Brown and Twiss and Hong, Ou, and Mandel. The quantum interference at beam splitters lies at the heart of what …
