Variational quantum algorithms to estimate rank, quantum entropies, fidelity and Fisher information via purity minimization
Kok Chuan Tan, Tyler Volkoff
Variational quantum algorithms (VQAs) that estimate values of widely used physical quantities such as the rank, quantum entropies, the Bures fidelity and the quantum Fisher informa…
Error mitigation in quantum metrology via zero noise extrapolation
Zhuo Zhao, Kok Chuan Tan
We consider Zero Noise Extrapolation (ZNE) as an error mitigation strategy in quantum metrology. It is shown that noise expansion can be systematically performed over sufficiently…
Quantum stochastic series expansion methods
Kok Chuan Tan, Dhiman Bowmick, Pinaki Sengupta
A quantum implementation of the Stochastic Series Expansion (SSE) Monte Carlo method is proposed, and it is shown that quantum SSE offers significant advantages over classical impl…
Fast quantum imaginary time evolution
Kok Chuan Tan
A fast implementation of the quantum imaginary time evolution (QITE) algorithm called Fast QITE is proposed. The algorithmic cost of QITE typically scales exponentially with the nu…
Identifying quantum phase transitions via geometric measures of nonclassicality
Kok Chuan Tan
In this article, we provide theoretical support for the use of geometric measures of nonclassicality as a general tool to identify quantum phase transitions. We argue that divergen…
Nonclassical Light and Metrological Power: An Introductory Review
Kok Chuan Tan, Hyunseok Jeong
In this review, we introduce the notion of quantum nonclassicality of light, and the role of nonclassicality in optical quantum metrology. The first part of the paper focuses on de…
