It’s certainly been a cold week in Colorado, and the state was home to one of the coldest places in the universe. But people didn’t feel it. Rather, it’s in a quantum dilution refrigerator at the Colorado School of Mines in Golden.

Dropping below 400 degrees Fahrenheit, the fridge created by Maybell Quantum CEO Corban Tillemann-Dick, aims to advance quantum engineering.

“It kind of looks like a weird fridge, and, candidly, it is a weird fridge. It’s a really special, weird fridge that gets, again, unimaginably cold inside,” Tillemann-Dick said. “What we’ve done is we’ve taken that room size tangle of tubes and wires, and we’ve turned it into a couple 19-inch racks, a system you can roll through a door, plug in, turn on, and, suddenly, you have the coldest place in the known universe, just a few feet away from you.”
