CTOnews.com, May 11 / PRNewswire-FirstCall-Asianet /-- American Quantinum researchers say they have "created" an Anyons on a quantum processor for the first time, claiming to have opened "a reliable path to fault-tolerant quantum computing."

According to reports, the researchers used a new quantum processor called H2, which uses ytterbium and barium ions to create qubits through magnetic field and laser capture. It is said that the H2 quantum processor has 32 fully connected high-fidelity qubits and parallel gate region architecture, which is a new type of ion trap and its oval shape is similar to the "runway".

The team weaves these qubits into a Borromeo-like pattern (a topological network of staggered triangles) and finds that the quantum mechanical properties of the qubits are the same as the predicted anyons. This is the topological quantum state that physicists have been looking for for a long time.

▲ H2 quantum processor CTOnews.com found that the results have been published in journals such as Nature and Quantum Physics (DOI:10.1038/d41586-023-01574-0), describing a novel approach to "ghostly teleaction".

The focus of quantum research is to try to connect the entangled qubits by constructing a continuous structure of non-Abel Anyons, which is similar to the Boromeo chain: particles move around each other's circular modes. maximize the distance between particles (which helps to improve coherent time) and make them more anti-jamming.

In short, the team demonstrated the quantum entanglement of 32 ion-based qubits.

"No pair of particles revolves around each other, but all the particles are connected," said Ashvin Vishwanath, a theoretical physicist at Harvard University and co-author of the paper. "it's really an amazing state of matter, which we don't realize very clearly in any other setting."

"there is great mathematical beauty in this physical system," said Steven Simon, a theoretical physicist at the University of Oxford in England, commenting on the paper in Nature. "it's incredible to see them realized for the first time for a long time."

Michael Manfra, an experimental physicist at Purdue University, told Nature that Quantinuum's machines did not really create non-Abel Anyons, but only simulated their properties (and only some of them). Quantinuum agrees-but they stress that particles behave in a way that meets the definition of a non-Abel Anyon and meets the requirements of fault-tolerant quantum computing systems.

Therefore, although more research may be needed on the "trusted path", it is clear that the result of this study is undoubtedly a great achievement.

Interestingly, Quantinuum's research has found a way to fault-tolerant quantum computers, but this conflicts with Microsoft's own research, which also pursues topological qubits in its quantum computing work, a quantum system different from Quantum's early ion chain qubits and IBM superconducting qubits.

For now, although Quantinuum's method simulates the topological behavior of non-abelian qubits to take advantage of the influence of "Borromean rings" on robustness, Microsoft is pursuing qubits made up of physical Anyons themselves-an approach that offers more benefits than Quantinuum.
