  • Quantum computers are wondrous because they operate on quantum mechanics.
  • Quantinuum unveiled a new one in a Denver data center and invited a small crew of people to see it.
  • The computer looked like a very sophisticated science experiment.

A drab, vinyl-floored, windowless office building just north of Denver houses one of the wonders of the computer industry. It's home to several wonders, actually: a data center where two commercial-quantum computers are operating for paying customers including JPMorgan, and a third prototype under construction.
