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…
Relation between nonclassical features through logical qudits
Sooryansh Asthana, V. Ravishankar
Scalable modern-time fault-tolerant quantum computation and quantum communication in a network employ a large number of physical qubits. For example, IBM is reported to have made a…
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…
Boosted quantum and semi-quantum communication protocols
Rajni Bala, Sooryansh Asthana, V. Ravishankar
Secure quantum communication protocols based on a prepare-and-measure scheme employ mutually unbiased bases. In these protocols, many runs, in which different participants measure…
