Physicists observe quantum properties in the world of objects

“If I took a tuning fork and wanted to get it to the quantum ground state, I would have to cool it below 50 billionths of a kelvin,” he explains. “There is no technology that will allow you to do that, not now. But if you push the frequency of that tuning fork up” by orders of magnitude, “then you only have to cool it to 50 millionths of a degree above absolute zero."
