“With this approach, we don’t try to eliminate noise in the surroundings; instead, we “trick” the system into thinking it doesn’t experience the noise,” first author Kevin Miao, postdoctoral researcher at UChicago, said in the statement.
They used both electromagnetic pulses and a continuous alternating magnetic field to keep the quantum system under control. They then tuned this magnetic field in just such a way, that the rest of the noise was simply tuned out.
“To get a sense of the principle, it’s like sitting on a merry-go-round with people yelling all around you,” Miao explained in the statement. “When the ride is still, you can hear them perfectly, but if you’re rapidly spinning, the noise blurs into a background.”
