Complexity theory is a fundamental branch of theoretical computer science that categorises computational problems according to their inherent difficulty and the resources required to solve them. At ...

For decades, the graph isomorphism problem has held a special status within complexity theory. While thousands of other computational problems have meekly succumbed to categorization as either hard or ...

A team of researchers at the Osaka City University Graduate School of Science continue to improve their recently developed quantum algorithm, this time by applying it to calculate the potential energy ...
