Quantum channels and some absolute properties of quantum states
Tapaswini Patro, Kaushiki Mukherjee, Nirman Ganguly
Environmental interactions are ubiquitous in any real-world application of a quantum information processing protocol. Such interactions result in depletion of quantum resources. Tw…
Hidden Steering Nonlocality in Quantum Networks
Kaushiki Mukherjee, Biswajit Paul, Soma Mandal
By combining two objects with no quantum effect one can get an object with quantum effect. Such a phenomenon, often referred to as activation has been analyzed for the notion of st…
Detecting Nontrilocal Correlations In Triangle Networks
Kaushiki Mukherjee
Correlations in quantum networks with independent sources exhibit a completely novel form of nonclassicality in the sense that the nonlocality of such correlations can be demonstra…
Hidden Non n-locality In Linear Networks
Kaushiki Mukherjee, Soma Mandal, Tapaswini Patro +1
We study hidden nonlocality in a linear network with independent sources. In the usual paradigm of Bell nonlocality, there are certain states which exhibit nonlocality only after t…
Persistency of non-n-local correlations in noisy linear networks
Kaushiki Mukherjee, Indranil Chakrabarty, Ganesh Mylavarapu
Linear n-local networks are compatible with quantum repeaters based entanglement distribution protocols. Different sources of imperfections such as error in entanglement generation…
Absolute fully entangled fraction from spectrum
Tapaswini Patro, Kaushiki Mukherjee, Mohd Asad Siddiqui +2
Fully entangled fraction (FEF) is a significant figure of merit for density matrices. In bipartite quantum systems, the threshold value FEF , carries signi…
Characterizing Quantum Correlations In Fixed Input -Local Network Scenario
Kaushiki Mukherjee, Biswajit Paul, Arup Roy
Contrary to Bell scenario, quantum nonlocality can be exploited even when all the parties do not have freedom to select inputs randomly. Such manifestation of nonlocality is possib…
Restricted Distribution of Quantum Correlations in Bilocal Network
Kaushiki Mukherjee, Biswajit Paul, Debasis Sarkar
Analyzing shareability of correlations arising in any physical theory may be considered as a fruitful technique of studying the theory. Our present topic of discussion involves an…
Nontrilocality: Exploiting nonlocality from three particle systems
Kaushiki Mukherjee, Biswajit Paul, Debasis Sarkar
In Phys. Rev. Lett. \textbf{104},170401 (2010), Branciard \textit{e.t al.} first characterized the correlations arising in an entanglement swapping network under the assumption tha…
Nonlocality of three-qubit Greenberger-Horne-Zeilinger-symmetric states
Biswajit Paul, Kaushiki Mukherjee, Debasis Sarkar
Mixed states appear naturally in experiment over pure states. So for studying different notions of nonlocality and their relation with entanglement in realistic scenarios, one need…
The Quadratic Spin Squeezing Operators
P. K. Pathak, R. N. Deb, N. Nayak +1
We discuss generic spin squeezing operators (quadratic in angular momentum operators) capable of squeezing out quantum mechanical noise from a system of two-level atoms (spins) in…
