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…
Catalytic Transformations in Coherence Theory
Priyabrata Char, Dipayan Chakraborty, Amit Bhar +2
In 2016, A. Winter et al.(Physical Review Letters 116 (12) (2016) 120404) provided an operational meaning to relative entropy of coherence and coherence of formation by introducing…
Necessary and Sufficient Condition for the Equivalence of Two Pure Multipartite States under Stochastic Local Incoherent Operations and Classical Communications
Dipayan Chakraborty, Prabir Kumar Dey, Nabendu Das +3
Resource theory of quantum coherence originated like entanglement in quantum information theory. However, still now proper classification of quantum states is missing under coheren…
Structure of Resource Theory of Block Coherence
Prabir Kumar Dey, Dipayan Chakraborty, Priyabrata Char +3
Emerging from the superposition principle, the resource theory of coherence plays a crucial role in many information-processing tasks. Recently, a generalization to this resource t…
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…
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…
Effect of local filtering on Freezing Phenomena of Quantum Correlation
Sumana Karmakar, Ajoy Sen, Amit Bhar +1
General quantum correlations measures like quantum discord, one norm geometric quantum discord, exhibit freezing, sudden change, double sudden change behavior in their decay rates…
Local Quantum Uncertainty and Bounds on Quantumness for Orthogonally invariant class of states
Ajoy Sen, Amit Bhar, Debasis Sarkar
Local quantum uncertainty (in short LQU) was introduced by Girolami et. al.(Phy. Rev. Lett. \textbf{110}, 240402) as a measure of quantum uncertainty in a quantum state as achievab…
Character of superposed states under deterministic LOCC
Amit Bhar, Ajoy Sen, Debasis Sarkar
In this paper we investigate the effect of superposition of states on local conversion of pure bipartite states under deterministic LOCC. We are able to form a bridge between compa…
Decoherence Dynamics of Measurement-Induced Nonlocality and comparison with Geometric Discord for two qubit systems
Ajoy Sen, Debasis Sarkar, Amit Bhar
We check the decoherence dynamics of Measurement-induced Nonlocality(in short, MIN) and compare it with geometric discord for two qubit systems. There are quantum states, on which…
Monogamy of Measurement Induced Non-Locality
Ajoy Sen, Debasis Sarkar, Amit Bhar
Measurement-Induced NonLocality was introduced by Luo and Fu (Phys. Rev. Lett. \textbf{106}, 120401,(2011)) as a measure of nonlocality in a bipartite state. In this paper we will…
No-Cloning and No-Deleting theorems through the existence of Incomparable states under LOCC
Amit Bhar, Indrani Chattopadhyay, Debasis Sarkar
No-Cloning and No-Deleting theorems are verified with the constraint on local state transformations via the existence of incomparable states. Assuming the existence of exact clonin…
