Quantum and semi--quantum key distribution in networks
Rajni Bala, Sooryansh Asthana, V. Ravishankar
In this paper, we utilize the potential offered by multidimensional separable states (MSS) for secure and simultaneous distributions of keys in a layered network. We present protoc…
Combating quantum errors: an integrated approach
Rajni Bala, Sooryansh Asthana, V. Ravishankar
Near-term quantum communication protocols suffer inevitably from channel noises, whose alleviation has been mostly attempted with resources such as multiparty entanglement or sophi…
Combating errors in propagation of orbital angular momentum modes of light in turbulent media
Rajni Bala, Sooryansh Asthana, V. Ravishankar
There is a wealth of simulation, experimental and analytical studies on propagation of orbital angular momentum (OAM) modes through atmospheric and oceanic turbulence.} Using the d…
Nonclassical features in higher-dimensional systems through logical qudits
Sooryansh Asthana, V. Ravishankar
In a recent work [S. Asthana. New Journal of Physics 24.5 (2022): 053026], we have shown the interrelation of different nonclassical correlations in multiqubit systems with quantum…
Integrated semi-quantum layered communication
Rajni Bala, Sooryansh Asthana, V. Ravishankar
In recent times, secure quantum communication in layered networks has emerged as an important area of study. In this paper, we harness the potential offered by multidimensional sta…
