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…
