Experimental Guesswork with Quantum Side Information using Twisted Light
Vishal Katariya, Narayan Bhusal, Chenglong You
The guesswork is an information-theoretic quantity which can be seen as an alternate security criterion to entropy. Recent work has established the theoretical framework for guessw…
Limits on Parameter Estimation of Quantum Channels
Vishal Katariya
The aim of this thesis is to develop a theoretical framework to study parameter estimation of quantum channels. We study the task of estimating unknown parameters encoded in a chan…
Geometric distinguishability measures limit quantum channel estimation and discrimination
Vishal Katariya, Mark M. Wilde
Quantum channel estimation and discrimination are fundamentally related information processing tasks of interest in quantum information science. In this paper, we analyze these tas…
Entropic Energy-Time Uncertainty Relation
Patrick J. Coles, Vishal Katariya, Seth Lloyd +2
Energy-time uncertainty plays an important role in quantum foundations and technologies, and it was even discussed by the founders of quantum mechanics. However, standard approache…
