A paper recently published in the journal Nature Physics by researchers affiliated with the Joint Center for Quantum Information and Computer Science (QuICS)—sheds new light on the intricate relationship between quantum resources and quantum algorithms, revealing that quantum resources can serve as a driving force for accelerating quantum simulation.
The research—highlighted on the cover of the August issue—shows that quantum simulation algorithms can be faster in the presence of entanglement.
Ultimately, the researchers hope this work can reduce the resource requirements for specific practical simulations in areas such as chemistry, condensed matter, and nuclear/particle physics.
The paper’s lead author is Qi Zhao, who was a Hartree Postdoctoral Fellow at QuICS from 2019–2022 and is currently an assistant professor of computer science at The University of Hong Kong. He collaborated on the paper with QuICS Fellow Andrew Childs, a professor of computer science at the University of Maryland and interim director of the University of Maryland Institute for Advanced Computer Studies (UMIACS).
You Zhou, an assistant professor of communication science and engineering at Fudan University in Shanghai, China also contributed to the paper.
