A quantum computer has successfully generated a mysterious particle called an anyon, which has the ability to remember its past. This discovery could potentially enhance the performance of quantum computers. Unlike other particles, anyons keep a record of their position even after being swapped. They are quasiparticles that exist in two dimensions and exhibit behaviors similar to particles. Non-Abelian anyons, a particular variety of anyons, retain a memory of the order in which they were swapped. This memory is crucial for quantum computing as it relies on the unique properties of anyons and entanglement. Previously, non-Abelian anyons had only been theoretical, but now a team of researchers at quantum computing firm Quantinuum claim to have experimentally created them using a new quantum processor called H2.
The team used ytterbium and barium ions trapped using magnetic fields and lasers to create qubits, the building blocks of a quantum computer. These qubits were entangled in a Kagome lattice pattern, similar to interlocking stars commonly seen in Japanese baskets. By manipulating the interactions between the qubits, equivalent to moving the anyons around, the researchers were able to observe the distinct changes in the anyons’ properties. This successful test confirms the presence of non-Abelian topological order, a significant advancement in the field of quantum computing.
However, there is some debate among experts regarding whether the team at Quantinuum has truly created non-Abelian anyons or if they have merely simulated them. Some researchers argue that a simulation lacks certain properties present in the real particles. Nonetheless, the lead researcher, Henrik Dryer, considers the simulation to be identical to the real thing due to the quasiparticle nature of anyons. According to Dryer, any system that can produce the required entanglement can create the same type of anyons.
This breakthrough not only paves the way for further advancements in quantum computing but also provides valuable insights into understanding the exotic state of matter and the properties of anyons.
