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

Error-immune quantum communication
Rajni Bala, V. Ravishankar
Environmental effects on the transmission of a state result, in general, in a change in the information carried by it. To mitigate this, many techniques such as quantum error--corr…
Quantum communication with invariant separable level systems
Sooryansh Asthana, Rajni Bala, V. Ravishankar
Information is encoded in a qubit in the form of its Bloch vector. In this paper, we propose protocols for remote transfers of information in a known and an unknown qubit to qudits…
