Researchers from UChicago PME, Harvard, Stony Brook and Quantinuum built and tested a complete set of quantum operations based on non-Abelian anyons, publishing results in Nature. The team says this is the first experimental proof that manipulating these exotic quasiparticles can perform any computation required for universal quantum computing.
Physicists at Chalmers University of Technology in Sweden devised a theoretical method that performs a wide range of advanced quantum operations more than a thousand times faster than current techniques. The approach targets the core problem that qubits are extremely fragile and prone to errors from noise, radiation, and heat during lengthy operations. The findings were published in Physical Review Letters.
IBM has released Nighthawk r2, a 120-qubit quantum processor now live on the IBM Quantum Platform, featuring a new high-speed qubit reset architecture that runs over 100,000 circuits per second, roughly 25 times the throughput of IBM's current Heron processors. The chip pairs 120 qubits with 218 couplers and 120 reset elements, and has already run circuits with more than 7,500 gates accurately, hitting a milestone IBM had targeted for 2026.
