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…
Negativity of quasiprobability distributions as a measure of nonclassicality
Kok Chuan Tan, Seongjeon Choi, Hyunseok Jeong
We demonstrate that the negative volume of any -paramatrized quasiprobability, including the Glauber-Sudashan -function, can be consistently defined and forms a continuous hi…
Quantum error correction assisted quantum metrology without entanglement
K. C. Tan, S. Omkar, H. Jeong
In this article we study the role that quantum resources play in quantum error correction assisted quantum metrology (QECQM) schemes. We show that there exist classes of such probl…
