A fundamental barrier to scaling quantum computing machines is "qubit interference." In new research published in Science Advances magazine, engineers and physicists from Rigetti Computing describe a breakthrough that can expand the size of practical quantum processors by reducing interference.
Matt Reagor, lead author of the paper, says: "We've developed a technique that enables us to reduce interference between qubits as we add more and more qubits to a chip, thus retaining the ability to perform logical operations that are independent of the state of a (large) quantum register."
