Is That Quantum Computer for Real? There May Finally Be a Test

Is That Quantum Computer for Real? There May Finally Be a Test - Wired Science: "In early May, news reports gushed that a quantum computation device had for the first time outperformed classical computers, solving certain problems thousands of times faster. The media coverage sent ripples of excitement through the technology community. A full-on quantum computer, if ever built, would revolutionize large swaths of computer science, running many algorithms dramatically faster, including one that could crack most encryption protocols in use today."
