Squeezing as a catalyst for non-Gaussian advantage in characterization of nonlinear media
Manju, Samaneh Hesabi, Siting Tang +2
We address the precise characterization of coupling strength of nonlinear media in continuous-variable (CV) quantum systems using coherent and squeezed vacuum states as Gaussian pr…
Beating noise in frequency estimation with squeezing and memory in continuous-variable systems
Ayan Patra, Manju, Aditi Sen De +1
Quantum metrology promises precision beyond classical limits, yet environmental noise typically degrades the quantum resources required for such enhancement. In this work, we inves…
OH molecule as a quantum probe to jointly estimate electric and magnetic fields
Luca Previdi, Francesco Albarelli, Matteo G. A. Paris
The hydroxyl radical, hereafter referred to as the OH molecule (OHM), carries both electric and magnetic dipole moments and, as a diatomic molecule, admits a comparatively simple a…
Statistical phase-space complexity of continuous-variable quantum channels
Siting Tang, Francesco Albarelli, Yue Zhang +2
The statistical complexity of continuous-variable quantum states can be characterized with a quantifier defined in terms of information-theoretic quantities derived from the Husimi…
Quantifying complexity of continuous-variable quantum states via Wehrl entropy and Fisher information
Siting Tang, Francesco Albarelli, Yue Zhang +2
The notion of complexity of quantum states is quite different from uncertainty or information contents, and involves the tradeoff between its classical and quantum features. In thi…
