Nonclassicality of Mixed States with Photon Number Coherence
Spencer Rogers, Salman Shahid, Wenchao Ge
The operational resource theory (ORT) measure is a nonclassicality measure for bosonic states, notable for its resource-theoretic properties and connection to metrology. However, i…
Classical-Nonclassical Polarity of Gaussian States
