A team led by researchers at the Flatiron Institute discovered a new phase of matter that has the potential to act as long-term quantum information storage.
The researchers subjected a quantum computer's qubits to "quasi-rhythmic laser pulses" based on the Fibonacci sequence, demonstrating a way of storing quantum information that is less prone to errors.
"With this quasi-periodic sequence, there's a complicated evolution that cancels out all the errors that live on the edge," says Flatiron's Philipp Dumitrescu, lead author of the article describing the work. "Because of that, the edge stays quantum-mechanically coherent much, much longer than you'd expect."
