Google says it has reached a major breakthrough in quantum computing research. Scientists reported Wednesday in the publication Nature about successful experiments involving quantum technology. The team said that, in one test, its quantum computer processor was able to complete a complex mathematical problem in just 200 seconds. The same problem would have taken the world’s fastest supercomputer 10,000 years to complete, the scientists said. Researchers described the new breakthrough as “quantum supremacy.” This term describes a point at which a quantum computer can perform a calculation that a traditional computer could never complete within its lifetime. Quantum computing is a still-developing technology that is designed to greatly speed up the processing of information.
