Detecting Two Qubit Both-Way Positive Discord States
Kaushiki Mukherjee, Sumana Karmakar, Biswajit Paul +1
Quantum discord plays a pragmatic role in analyzing nonclassical feature of quantum correlations beyond entanglement. It is used in several information processing protocols which l…
Several Trade off Features of Quantum Steering in Distributed Scenario
Arup Roy, Some Sankar Bhattacharya, Amit Mukherjee +3
In the present work, we address the question of how bipartite steering violation takes place among multi-partite systems (where each sub-system have Hilbert space dimension restric…
Bell-CHSH Violation Under Global Unitary Operations: Necessary and Sufficient conditions
Nirman Ganguly, Amit Mukherjee, Arup Roy +3
The relation between Bell-CHSH violation and factorization of Hilbert space is considered here. That is, a state which is local in the sense of the Bell-CHSH inequality under a cer…
Witness of mixed separable states useful for entanglement creation
Nirman Ganguly, Jyotishman Chatterjee, A. S. Majumdar
Absolutely separable states form a special subset of the set of all separable states, as they remain separable under any global unitary transformation unlike other separable states…
A cloned qutrit and its utility in information processing tasks
Sovik Roy, Nirman Ganguly, Atul Kumar +2
We, in this paper, analyze the efficacy of an output as a resource from a universal quantum cloning machine in information processing tasks such as teleportation and dense coding.…
Construction of optimal teleportation witness operators from entanglement witnesses
Satyabrata Adhikari, Nirman Ganguly, A. S. Majumdar
Teleportation witnesses are hermitian operators which can identify useful entanglement for quantum teleportation. Here we provide a systematic method to construct teleportation wit…
Entanglement witness operator for quantum teleportation
Nirman Ganguly, Satyabrata Adhikari, A. S. Majumdar +1
The ability of entangled states to act as resource for teleportation is linked to a property of the fully entangled fraction. We show that the set of states with their fully entang…
Common entanglement witnesses and their characteristics
Nirman Ganguly, Satyabrata Adhikari, A. S. Majumdar
We investigate the issue of finding common entanglement witness for certain class of states and extend this study to the case of Schmidt number witnesses. We also introduce the not…
Witness for edge states and its characteristics
Nirman Ganguly, Satyabrata Adhikari
Edge states lying at the edge of PPT entangled states have a very intriguing existence and their detection is equally interesting. We present here a new witness for detection of ed…
Deletion, Bell's Inequality, Teleportation
Indranil Chakrabarty, Nirman Ganguly, Binayak. S. Choudhury
In this letter we analyze the efficacy of the entangled output of Pati-Braunstein deletion machine [3] as a teleportation channel. We analyze the possibility of it violating the Be…
Teleportation via a mixture of a two qubit subsystem of a N-qubit W and GHZ state
Indranil Chakrabarty
In this work we study a state which is a random mixture of a two qubit subsystem of a -qubit W state and GHZ state. We analyze several possibilities like separability criterion…
Entanglement and Mixed ness of Locally Cloned Non - Maximal W - State
Indranil Chakrabarty, Sovik Roy, Nirman Ganguly +1
In this work we describe a protocol by which two of three parties generate two bipartite entangled state among themselves without involving third party, from a non maximal W state…
Hybrid Quantum Cloning Machine
Satyabrata Adhikari, A. K. Pati, Indranil Chakrabarty +1
In this work, we introduce a special kind of quantum cloning machine called Hybrid quantum cloning machine. The introduced Hybrid quantum cloning machine or transformation is nothi…
Impossibility of partial swapping of Quantum Information
Indranil Chakrabarty
It is a well known fact that a quantum state are represented by a point on the Bloch sphere, characterized by two parameters and . Here in this work, we find out…
Broadcasting of Inseparability
Satyabrata Adhikari, B. S. Choudhury, Indranil Chakrabarty
Suppose we are given an entangled pair and then one can ask how well we can produce two entangled pairs starting from a given entangled pair using only local operations. To give re…
Fisher Information: Quantum Uncertainty Relation
Indranil Chakrabarty
The paper deals with the reformulation of quantum uncertainty relation involving position and momentum of a particle on the basis of the Kerridge measure of inaccuracy and the Fish…
