Monogamy of entanglement of maximal dimension
Sumit Nandi
In the present paper, a trade off of sharing of entanglement between subsystems of a higher dimensional quantum state is derived. It is presented in terms of an inequality which is…
Genuine multipartite entanglement detection with mutually unbiased bases (MUBs)
Sumit Nandi
In the present paper, a novel framework to detect genuine multipartite entanglement (GME) has been presented by computing correlations in mutually unbiased bases (MUBs). It has bee…
Breaking Quantum Key Distributions under Quantum Switch-Based Attack
Sumit Nandi, Biswaranjan Panda, Pankaj Agrawal +1
Quantum key distribution (QKD) enables secure key sharing between distant parties, with several protocols proven resilient against conventional eavesdropping strategies. Here, we i…
Genuine entanglement detection via projection map in multipartite systems
Bivas Mallick, Sumit Nandi
We present a formalism to detect genuine multipartite entanglement by considering projection map which is a positive but not completely positive map. Projection map has been motiva…
