Quantum Tech Weekend Roundup: Forgotten Particle Breakthrough, DARPA’s Big Bet & a Million-Qubit Gambit (Aug 23–24, 2025)
USC mathematicians identified the “neglecton,” a previously ignored quasiparticle, as key to universal topological quantum computing, according to Nature Communications. University of Sydney researchers demonstrated a single-atom logic gate using GKP encoding, sharply reducing qubit overhead, as reported in Nature Physics. Chalmers and Aalto scientists developed a magnetic quantum material that shields qubits from noise, published in Physical Review Letters.
