Google claims that its quantum computer has been able to perform a calculation in a matter of seconds, a task that would take a traditional computer thousands of years. Even though quantum processors currently only handle simple problems, they are expected to have a significant impact on the future of the pharmaceutical, manufacturing, and banking industries.
Google’s recent article on quantum computing published in the scientific journal, Nature, has been a source of intense debate. The Mountain View company claims to have executed a computational task in 200 seconds (three minutes and 20 seconds). The operation involved performing a random sampling calculation, which would have taken the world’s most powerful supercomputer 10,000 years. This would be the first empirical demonstration of quantum supremacy, a term that describes the point where quantum computers have an unparalleled advantage over classical computers — when they can perform a task that classical computers cannot.(...)
