Quantum computers will capitalize on the mind-bending properties of quantum particles to perform complex calculations that are impossible for today’s traditional computers.

Using high magnetic fields, Susumu Takahashi, assistant professor in the USC Dornsife College of Letters, Arts and Sciences, and his colleagues managed to suppress decoherence, which is one of the key stumbling blocks in quantum computing.

“High magnetic fields reduce the level of the noises in the surroundings, so they can constrain the decoherence very efficiently,” Takahashi said. Decoherence has been described as a “quantum bug” that destroys fundamental properties that quantum computers would rely on.
