Improving device-independent quantum key distribution protocols through multiple routed Bell tests
Sujan Vijayaraj, Mauro Paternostro
Device-independent quantum key distribution (DI-QKD) offers security with the smallest possible set of assumptions about the experimental setup. The challenge posed by its implemen…
Can error in quantum deletion machines be beneficial for deletion?
Sujan Vijayaraj, S. Balakrishnan
In this paper, a generalized input state dependent deletion machine called probabilistic quantum deletion machine is proposed. Considering the Pati-Braunstein deletion machine as a…
Quasi-deterministic secure quantum communication using non-maximally entangled states
Sujan Vijayaraj, S. Balakrishnan, K. Senthilnathan
Quantum communication in general helps deter potential eavesdropping in the course of transmission of bits to enable secure communication between two or more parties. In this paper…
Impartial binary decisions through qubits
Sujan Vijayaraj, S. Nandakumar
Binary decisions are the simplest form of decisions that are made in our daily lives. Examples include choosing a two-way path in a maze, accepting or declining an offer, etc. Thes…
