A clever quantum algorithm has been designed to enable the study of a class of strongly interacting fermionic systems on a digitised quantum computer. Explaining how the advance will help to realise the applications of Quantum Computing, co-author and physicist Pouyan Ghaemi said: “Our research has developed a quantum algorithm which can be used to study a class of many-electron quantum systems using quantum computers. Our algorithm opens a new venue to use the new quantum devices to study problems which are quite challenging to study using classical computers. Our results are new and motivate many follow up studies,” reported City College of New York News.

This study will provide tools to improve quantum computing devices for which currently only limited tools are available, believes Ghaemi. It also holds to power to revolutionise the everyday life once quantum computers begin to be used for daily life applications.

Ghaemi added: “Quantum physics is the fundamental theory of nature which leads to formation of molecules and the resulting matter around us. It is already known that when we have a macroscopic number of quantum particles, such as electrons in the metal, which interact with each other, novel phenomena such as superconductivity emerge.”

The research, entitled “Creating and Manipulating a Laughlin-Type ν=1/3 Fractional Quantum Hall State on a Quantum Computer with Linear Depth Circuits,” has been published in the physical review journal “PRX Quantum” of the American Physical Society. The authors includes scientists from City College of New York, Western Washington University, UC Santa Barbara, Google AI Quantum, and University of Michigan.
