Quantum Computing Is Dead. Long Live Quantum Computing!

This is the year of quantum science and technology. Literally: The United Nations said so. But no amount of pomp and hype can make something true. The fact is, it’s been the year of quantum nearly every year for many, many years now. It’s always the next big thing. It’s always just about here. Well, is it? Really? Nearly a century ago, Erwin Schrödinger poked fun at quantum principles by comparing them to a cat that’s both alive and dead. Today, quantum computing finds itself in just such a state: a superposition of here and not-here, a series of world-changing breakthroughs that are, at the same time, also colossal letdowns. So what’s the real story? Let’s open the box and find out.
