What Quantum Supremacy Should Look Like if Google's Neven if Correct | NextBigFuture.com

The current state of noisy qubit quantum computers is a bit difficult to assess. Superconducting quantum chips and ion trapped quantum computers are in the 16 qubit to 100 qubit range. Rigetti Computing is seeking an application that will give it a practical advantage over conventional computers. Other companies are pushing other metrics to gauge progress. Google has said they are at 72 qubits but there are reports that that announcement in March 2018 was premature. There is only 20 qubit quantum computers that can be accessed via cloud computer interfaces. Google has stated that they went from laptops, to
