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.
Google Open-Source Quantum Computing Framework Cirq Reaches 1.0
After over four years in development, Google open source quantum programming framework Cirq has reached stability and established itself as the lingua franca that Google engineers use to write quantum programs for Google’s own quantum processors.
