Generation and entanglement study of generalized N-mode single photon perfect W-states
Manoranjan Swain, M. Karthick Selvan, Amit Rai +1
We consider single photon realization of generalized N-qubit perfect W-states which are suitable for perfect teleportation and superdense coding. We propose schemes to generate gen…
Coherence, Path-Predictability and I-Concurrence: A Triality
Abhinash Kumar Roy, Neha Pathania, Nitish Kumar Chandra +2
It is well known that fringe contrast is not a good quantifier of the wave nature of a quanton in multipath interference. A new interference visibility, based on the Hilbert-Schmid…
Absolutely Secure Distributed Superdense Coding: Entanglement Requirement for Optimality
Sagnik Dutta, Asmita Banerjee, Prasanta K. Panigrahi
Superdense coding uses entanglement as a resource to communicate classical information securely through quantum channels. A superdense coding method is optimal when its capacity re…
Quantum Blockchain Based on Dimensional Lifting Generalized Gram-Schmidt Procedure
Kumar Nilesh, P. K. Panigrahi
The advancement of quantum computers undermines the security of classical blockchain, necessitating either a post-quantum upgrade of the existing architecture or creation of an inh…
Experimental realization of BB84 protocol with different phase gates and SARG04 protocol
Sinchan Ghosh, Harsh Mishra, Bikash K. Behera +1
Cryptography in the modern era is very important to prevent a cyber attack, as the world tends to be more and more digitalized. Classical cryptographic protocols mainly depend on t…
Dynamics of tripartite correlations for three qubits in independent thermal reservoirs
Sourabh Magare, Abhinash Kumar Roy, Prasanta K. Panigrahi
We investigate the dynamical evolution of multipartite entanglement in tripartite systems with three qubits present in independent thermal reservoirs, modelled as infinite set of q…
