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…
Quantum State Discrimination Circuits Inspired by Deutschian Closed Timelike Curves
Christopher Vairogs, Vishal Katariya, Mark M. Wilde
It is known that a party with access to a Deutschian closed timelike curve (D-CTC) can perfectly distinguish multiple non-orthogonal quantum states. In this paper, we propose a pra…
RLD Fisher Information Bound for Multiparameter Estimation of Quantum Channels
Vishal Katariya, Mark M. Wilde
One of the fundamental tasks in quantum metrology is to estimate multiple parameters embedded in a noisy process, i.e., a quantum channel. In this paper, we study fundamental limit…
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…
Evaluating the Advantage of Adaptive Strategies for Quantum Channel Distinguishability
Vishal Katariya, Mark M. Wilde
Recently, the resource theory of asymmetric distinguishability for quantum strategies was introduced by [Wang et al., Phys. Rev. Research 1, 033169 (2019)]. The fundamental objects…
Guesswork with Quantum Side Information
Eric P. Hanson, Vishal Katariya, Nilanjana Datta +1
What is the minimum number of guesses needed on average to correctly guess a realization of a random variable? The answer to this question led to the introduction of the notion of…
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…
