Quantifying non-Gaussianity of bosonic fields via an uncertainty relation

2020 · Physical Review A

While Gaussian states and associated Gaussian operations are basic ingredients and convenient objects for continuous-variable quantum information, it is also realized that non-Gaussianity is an important resource for quantum information processing. The characterization and quantification …

Separability criteria based on a class of symmetric measurements

2023 · Communications in Theoretical Physics

Abstract Highly symmetric quantum measurements, such as mutually unbiased measurements (MUMs) and general symmetric informationally complete positive-operator-valued measures (GSIC-POVMs), play an important role in both foundational and practical aspects of quantum information theory. Recently, a …
