Efficient nonlinear witnessing of non-absolutely separable states with lossy detectors
Ayan Patra, Shiladitya Mal, Aditi Sen De
Entangled states are undoubtedly an integral part of various quantum information processing tasks. On the other hand, absolutely separable states which cannot be made entangled und…
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…
Self-testing of binary Pauli measurements requiring neither entanglement nor any dimensional restriction
Ananda G. Maity, Shiladitya Mal, Chellasamy Jebarathinam +1
Characterization of quantum devices received from unknown providers is a significant primary task for any quantum information processing protocol. Self-testing protocols are design…
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…
Unifying Two Notions of Nonlocality in Quantum Theory
Shiladitya Mal, Aditi Sen De
Ensembles containing orthogonal product states are found to be indistinguishable under local operations and classical communication (LOCC), thereby showing irreversibility in the p…
Detection loophole in measurement-device-independent entanglement witness
Kornikar Sen, Chirag Srivastava, Shiladitya Mal +2
There always exists an entanglement witness for every entangled quantum state. Negativity of the expectation value of an entanglement witness operator guarantees entanglement of th…
