Construction of PPT entangled state and its detection by using second-order moment of the partial transposition
Rohit Kumar, Satyabrata Adhikari
We adopt a formalism by which we construct and detect a new family of positive partial transpose entangled states in dimensional system. Our detection method is ba…
Geometric Discord of any arbitrary dimensional bipartite system and its application in quantum key distribution
Rashi Jain, Satyabrata Adhikari
Entangled quantum states are regarded as a key resource in quantum key distribution (QKD) protocols. However, quantum correlations, other than entanglement can also play a signific…
Classification of three-qubit genuine entangled states using concurrence fill
Shruti Aggarwal
Despite the successful experimental generation and verification of genuine multipartite entanglement, several existing entanglement measures remain insufficient to reliably capture…
Condition for the generation of the secret key in a BB84 like quantum key distribution protocol
Rashi Jain, Satyabrata Adhikari
Woodhead [Phys. Rev. A 88, 012331 (2013)] derived the lower bound of the secret key rate for a Bennett-Brassard (BB84) like quantum key distribution protocol under collective attac…
Quantum cloning transformation unlocks the potential of W class of states in a quantum secure direct communication protocol
Rashi Jain, Satyabrata Adhikari
In a controlled quantum secure direct communication (Controlled QSDC) protocol between three parties, the sender sends the encoded secured message to one of the two receivers, whic…
Modified Six State Cryptographic Protocol with Entangled Ancilla States
Rashi Jain, Satyabrata Adhikari
In a realistic situation, it is very difficult to communicate securely between two distant parties without introducing any disturbances. These disturbances might occur either due t…
