Exotic particles called nonabelions could fix quantum computers’ error problem.

“This is the credible path to fault-tolerant quantum computing,” says Tony Uttley, Quantinuum’s president and chief operating officer.

Quantinuum’s approach has an advantage: compared with most other types of qubits, the ions in its trap can be moved around and brought to interact with each other, which is how quantum computers perform computations.The physicists exploited this flexibility to create an unusually complex form of quantum entanglement, in which all 32 ions share the same quantum state.
