Multipartite Monogamy of Entanglement for Three Qubit States
Priyabrata Char, Dipayan Chakraborty, Prabir Kumar Dey +4
The distribution of entanglement in a multiparty system can be described through the principles of monogamy or polygamy. Monogamy is a fundamental characteristic of entanglement th…
Coherence Fraction
Sumana Karmakar, Ajoy Sen, Indrani Chattopadhyay +2
The concept of entanglement fraction is generalized to define coherence fraction of a quantum state. Precisely, it quantifies the proximity of a quantum state to maximally coherent…
Performance of quantum cloning and deleting machines over coherence
Sumana Karmakar, Ajoy Sen, Debasis Sarkar
Coherence, being at the heart of interference phenomena, is found to be an useful resource in quantum information theory. Here we want to understand quantum coherence under the com…
Persistency of Genuine Correlations Under Particle Loss
Biswajit Paul, Kaushiki Mukherjee, Ajoy Sen +4
In a recent work [\href{http://journals.aps.org/pra/abstract/10.1103/PhysRevA.86.042113}{Phys. Rev. A 86, 042113 (2012)}] the question of persistency of entanglement and nonlocalit…
On Strong Monogamy Conjecture in Four-Qubit System
Sumana Karmakar, Ajoy Sen, Amit Bhar +1
Monogamy is a defining feature of entanglement, having far reaching applications. Recently, Regula \textit{et.al.} in Phys. Rev. Lett. \textbf{113}, 110501(2014) have proposed a st…
Local Quantum Uncertainty in Two-Qubit Separable States: A Case Study
Ajoy Sen, Debasis Sarkar, Amit Bhar
Recent findings suggest, separable states, which are otherwise of no use in entanglement dependent tasks, can also be used in information processing tasks that depend upon the disc…
