Quantum computing firm D-Wave has announced this month its largest ever quantum chip containing 2,000 qubits — double the capacity of its previous biggest system. The chip is scheduled to ship next year, and if it lives up to its promise, it would solidify D-Wave’s position at the forefront of quantum computing, a potentially revolutionary field that would change computing as we know it.

And, more damningly, that using the company's current methodologies, it never will.
D-Wave’s Colin Williams, the company’s director of business development and a former quantum computing scientist himself, is bullish. "[The new chip] isn’t just bigger," he told The Verge. "It’s improved in many other ways."
