Latent optical nonclassicality of conditionally prepared states
arXiv:2408.04740 · doi:10.1103/PhysRevA.111.053701
Abstract
The lack of information obtained from informationally incomplete quantum measurements can prevent the detection of quantum resources, such as optical nonclassicality. We develop a technique that overcomes this limitation for single-mode quantum states conditionally prepared through measurements on another mode of a two-mode state. This task is performed by testing steering of latent nonclassicality -- a class of correlations beyond quantum entanglement and quantum discord -- for which we introduce a rigorous description.
