Coherent Control of Channel Dilations Activate Temporal Bell Nonclassicality
H S Karthik, Akshata Shenoy H, A R Usha Devi +1
The temporal Clauser-Horne-Shimony-Holt (CHSH) inequality witnesses the nonclassicality of temporal correlations, but its violation is generally degraded by environmental noise. He…
