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…
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…
State transfer with separable optical beams and variational quantum algorithms with classical light
Sooryansh Asthana, V. Ravishankar
Classical electromagnetic fields and quantum mechanics -- both obey the principle of superposition alike. This opens up many avenues for simulation of a large variety of phenomena…
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…
