Google achieves Quantum Supremacy
In a research paper first seen by the Financial Times, Google seems to claim that it achieved its long-proposed goal of “quantum supremacy.” This marks a major milestone in quantum computing, and it begins the era in which quantum computers can start out-performing classical supercomputers for various applications.
The idea that quantum computers could efficiently solve a computation that a classical computer can only solve inefficiently, is known as Quantum Supremacy.
