Indispensability of orbital angular momentum states in secure quantum communication tasks
Rajni Bala, Sooryansh Asthana
Quantum key distribution protocols have been designed for layered networks employing multidimensional entangled and separable orbital angular momentum states [Phys. Rev. A 97, 0323…
Quantum secure direct communication with SU(2) invariant separable polarisation- OAM states
Sooryansh Asthana, Rajni Bala, V. Ravishankar
We propose a quantum secure direct communication protocol using SU (2)- invariant separable states, identified as separable equivalents of two-qubit entangled Werner st…
Collaborative error-immune information transfer with OAM modes of light in networks through atmospheric turbulence
Rajni Bala, Sooryansh Asthana, V. Ravishankar
We present a protocol for collaborative error-immune information through atmospheric turbulence. The protocol allows transferring of information in a network of three participants.
Task-dependent semi-quantum secure communication in layered networks with OAM states of light
Rajni Bala, Sooryansh Asthana, V. Ravishankar
Secure communication in layered networks having differently preferred participants has attracted a lot of research attention. Protocols for key distribution in a layered network ha…
