Classical simulation of boson sampling based on graph structure
Changhun Oh, Youngrong Lim, Bill Fefferman +1
Boson sampling is a fundamentally and practically important task that can be used to demonstrate quantum supremacy using noisy intermediate-scale quantum devices. In this work, we…
Distributed quantum phase sensing for arbitrary positive and negative weights
Changhun Oh, Liang Jiang, Changhyoup Lee
Estimation of a global parameter defined as a weighted linear combination of unknown multiple parameters can be enhanced by using quantum resources. Advantageous quantum strategies…
Quantum Metrological Power of Continuous-Variable Quantum Networks
Hyukgun Kwon, Youngrong Lim, Liang Jiang +2
We investigate the quantum metrological power of typical continuous-variable (CV) quantum networks. Particularly, we show that most CV quantum networks provide an entanglement to q…
Classical simulation of bosonic linear-optical random circuits beyond linear light cone
Changhun Oh, Youngrong Lim, Bill Fefferman +1
Sampling from probability distributions of quantum circuits is a fundamentally and practically important task which can be used to demonstrate quantum supremacy using noisy interme…
Classical simulation of lossy boson sampling using matrix product operators
Changhun Oh, Kyungjoo Noh, Bill Fefferman +1
Characterizing the computational advantage from noisy intermediate-scale quantum (NISQ) devices is an important task from theoretical and practical perspectives. Here, we numerical…
