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…
Phase-space complexity of discrete-variable quantum states and operations
Siting Tang, Shunlong Luo, Matteo G. A. Paris
We introduce a quantifier of phase-space complexity for discrete-variable (DV) quantum systems. Motivated by a recent framework developed for continuous-variable systems, we constr…
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…
