Quantum computing’s “dark horse” just proved it can go universal

Their results provide the first experimental demonstration that this approach can support the broad range of operations required for universal quantum computing.

A Possible Shortcut Around Costly Quantum Error Correction The strategy could do more than help create a general-purpose quantum computer.

These error correction methods can preserve data, but they usually do not provide every operation needed to perform universal quantum computation on that protected information.

"Non-Abelian codes are a dark horse in the race to quantum error correction," said Henrik Dreyer, managing director and scientific lead at Quantinuum's Munich office and a co-author of the study.

Verresen is already working with other PME researchers on new techniques for stabilizing non-Abelian quantum memories.
