### Google and IBM Clash Over Milestone Quantum Computing Experiment

Today Google announced that it achieved “quantum supremacy.” Its chief quantum computing rival, IBM, said it hasn’t. The disagreement hinges on what the term really means.

### Why I Called It ‘Quantum Supremacy’

Researchers finally seem to have a quantum computer that can outperform a classical computer. But what does that really mean?

### To Invent a Quantum Internet

Fifty years after the current internet was born, the physicist and computer scientist Stephanie Wehner is planning and designing the next internet — a quantum one.

### Quantum Supremacy Is Coming: Here’s What You Should Know

Researchers are getting close to building a quantum computer that can perform tasks a classical computer can’t. Here’s what the milestone will mean.

### How to Turn a Quantum Computer Into the Ultimate Randomness Generator

Pure, verifiable randomness is hard to come by. Two proposals show how to make quantum computers into randomness factories.
