Quantum Computing Advance Begins New Era, IBM Says

Because of their intrinsic ability to consider many possibilities at once, quantum computers do not have to be very large to tackle certain prickly problems of computation, and on Wednesday, IBM researchers announced that they had devised a method to manage the unreliability in a way that would lead to reliable, useful answers. From a report: "What IBM showed here is really an amazingly important step in that direction of making progress towards serious quantum algorithmic design," said Dorit Ah
