D-Wave is the latest quantum computing company to say it has achieved “quantum supremacy,” better known as the ability to solve a problem with a quantum computer that can’t be done with a traditional computer. The Palo Alto, Calif.-based company published a paper in the scientific journal Science on Wednesday, which outlines how it accomplished a materials simulation that it says is beyond the reach of today’s traditional, or classical computers, which store and process information using binary digits, or bits. “This, in some sense, is the holy grail for quantum computing,” said Alan Baratz, chief executive of D-Wave. The news marks the most recent salvo in the war among both tech giants and startups to establish quantum supremacy—and therefore the value of quantum computers—that has been going since at least 2019, when Google said it had achieved the milestone. More recently, Google and Amazon each announced their own quantum chips while Microsoft in February said it created a new state of matter to help make quantum computers more powerful.
