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…

Dicke superposition probes for noise-resilient Heisenberg and super-Heisenberg Metrology
Sudha, B. N. Karthik, K. S. Akhilesh +1
Phase sensing with entangled multi-qubit states in the presence of noise is a central theme of modern quantum metrology. The present work investigates Dicke state superposition pro…
