A research team has developed new techniques for controlling qubits, which could help improve the accuracy of quantum computers.

The team, which included two physicists from the University of Oregon (UO), along with colleagues from the National Institute of Standards and Technology, the University of Colorado, Boulder, Lawrence Livermore National Laboratory, and the University of Texas at San Antonio, demonstrated that creating logic gates using magnetic forces is less expensive and more practical than using lasers to control trapped-ion qubits.

The researchers said their goal is to achieve 10,000 operations without error, as well as implementing layers of checks to resolve errors as they arise.

UO's David Allcock said, "We want to get to that point. Then you can use quantum computers for something useful. Right now, they're just toys."
