Researchers have developed a general quantum algorithm that can directly calculate the energy difference of an atom and molecule using a quantum computer. By avoiding the need to calculate the total molecular energies, the general algorithm is expected to be applied not only to quantum chemical calculations but also to various physical and mathematical problems, which are intractable with nowadays classical computers.

Holger F. Hofmann, professor in the Graduate School of Advanced Science and Engineering, Hiroshima University, published a method to experimentally demonstrate the precision of quantum measurements on Feb. 3 in Physical Review Research. His work has implications for our fundamental understanding of physics at the level of individual quantum objects.
