Google aims to show quantum supremacy with a 49-qubit chip by the end of 2017
Due 2017
IEEE Spectrum reported in May 2017 that Google's quantum hardware team aimed to build a 7-by-7 array of 49 superconducting qubits by the end of that year and use it to show "quantum supremacy": a calculation beyond the reach of the best supercomputers.

Quantum Supremacy Using a Programmable Superconducting Processor
“Today we published the results of this quantum supremacy experiment in the Nature article, “Quantum Supremacy Using a Programmable Superconducting Processor”. We developed a new 54-qubit processor, named “Sycamore”, that is comprised of fast, high-fidelity quantum logic gates, in order to perform the benchmark testing.”

Google Plans to Demonstrate the Supremacy of Quantum Computing
“By the end of this year, the team aims to increase the number of superconducting qubits it builds on integrated circuits to create a 7-by-7 array. With this quantum IC, the Google researchers aim to perform operations at the edge of what's possible with even the best supercomputers, and so demonstrate “quantum supremacy.””

Google and IBM Battle for Quantum Supremacy
“At a recent meeting of the American Physical Society in March, he laid out a path to building a 49-qubit computer before the end of the year. Martinis believes 49 qubits should be enough to demonstrate quantum supremacy”
