Combinatorial structures in quantum correlation: A new perspective
Rohit kumar, Satyabrata Adhikari
Graph-theoretic structures play a central role in the description and analysis of quantum systems. In this work, we introduce a new class of quantum states, called -graph stat…
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…
Realignment Criterion: A necessary and sufficient condition for two-qubit -states
Amish Gogia, Aakhyat Bagga, Satyabrata Adhikari +1
The Computable Cross Norm (CCN), or realignment criterion, is a widely used method for entanglement detection in quantum systems; however, it typically provides only a necessary co…
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…
Quantum key distribution using intra-particle entanglement
S. Adhikari, Dipankar Home, A. S. Majumdar +3
We propose the use of intra-particle entanglement to enhance the security of a practical implementation of the Bennett-Brassard-1984 (BB84) quantum key distribution scheme. Intra-p…
Quantum entanglement in a non-commutative system
S. Adhikari, B. Chakraborty, A. S. Majumdar +1
We explore the effect of two-dimensional position-space non-commutativity on the bipartite entanglement of continuous variable systems. We first extend the standard symplectic fram…
Teleportation of two-mode squeezed states
S. Adhikari, A. S. Majumdar, N. Nayak
We consider two-mode squeezed states which are parametrized by the squeezing parameter and the phase. We present a scheme for teleporting such entangled states of continuous variab…
