A dust-speck-sized coil, passing a current of millionths of an ampere, shifts the resonator's frequency by a billion cycles per second. This contrast turns the chip into an ideal tool for quantum computers and magnetic spectroscopy.

The method allows particles to float in a magnetic field and behave like a dancer who is in two places at once. These experiments will help us understand the boundary between the quantum and classical worlds, and possibly detect dark matter.
