Google says it has reached ‘quantum advantage’. What does that mean?

This quantum computer has run a verifiable algorithm 13,000 times faster than the world’s fastest ‘classical’ supercomputer, says Google, making what the company calls a ‘significant step’ towards the first real-world applications of quantum computing. But what might we realistically expect in the near future? In this video, UC Berkeley professors Umesh Vazirani and Dan Stamper-Kurn discuss the possibilities of quantum technology.
