Happy World Quantum Day! We are a group of quantum science researchers at the University of Maryland (UMD), and we’re back for a fourth year to answer more of your quantum questions. There’s always new quantum science to learn, so ask us anything!

We will be answering questions live on r/AskScience from 2:30 p.m. to 4:30 p.m. Eastern time on April 14, 2025. We will post our thread that morning, and once the post is live, the following link will lead to it.
