Google Claims Achievement of Quantum Supremacy, But IBM Issues Rebuttal
In a recent paper, Google researchers claim they programmed a quantum processor to perform a task that would require 10,000 years on a state-of-the-art classical supercomputer. Google's claim did not entirely persuade IBM researchers, who proposed an ideal simulation of the quantum task which, they argue, only requires 2.5 days on a classical computer and provides greater fidelity.

Quantum Advantage Formally Proved for Short-Depth Quantum Circuits
Researchers from IBM T. J. Watson Research Center, the University of Waterloo, Canada, and the Technical University of Munich, Germany, have proved theoretically that quantum computers can solve certain problems faster than classical computers. The algorithm they devised fits the limitations of current quantum computing processors, and an experimental demonstration may come soon.
