Einstein called it spooky action at a distance. He meant quantum entanglement, and he thought it couldn't be real. He was wrong! I publ...

In my last post , I laid out the fiber problem: quantum networks can't use classical repeaters because the no-cloning theorem forbids co...

Every quantum network built so far runs into the same wall: how do you move a quantum state across distance without destroying the property ...

Chapter 3 of Quantum from the Ground Up makes one argument: the physics works, and the engineering catches up slowly, one specialized syste...

Chapter 5 of Quantum From The Ground Up covers superconducting qubits: Josephson junctions, the Dolan bridge fabrication technique, and IBM...

I found a bunch of posts I started writing years ago but never finished. Here’s one of them.... just finished. I remember Mrs. Anderson at t...

Last week during a workshop on AI tools in the classroom at Pace University, a faculty member asked about AI and water use. I expected the q...
