Noisy quantum input loophole in measurement-device-independent entanglement witnesses
Kornikar Sen, Chirag Srivastava, Shiladitya Mal +2
Entanglement witnesses form an effective method to locally detect entanglement in the laboratory without having the prior knowledge of the full density matrix. However, separable s…
Performance of Dense Coding and Teleportation for Random States --Augmentation via Pre-processing
Rivu Gupta, Shashank Gupta, Shiladitya Mal +1
In order to understand the resourcefulness of a natural quantum system in quantum communication tasks, we study the dense coding capacity (DCC) and teleportation fidelity (TF) of H…
Hierarchies of localizable entanglement due to spatial distribution of local noise
Ratul Banerjee, Amit Kumar Pal, Aditi Sen De
Complete characterization of a noisy multipartite quantum state in terms of entanglement requires full knowledge of how the entanglement content in the state is affected by the spa…
