Neuroscientists are discovering that traveling waves of electrical activity in the brain are far more complex and functionally important than previously understood. New research using high-resolution intracranial recordings reveals diverse wave patterns—including source, sink, and spiral waves—that correspond to different behavioral tasks and may help the brain reorganize in real time to meet behavioral demands.
Researchers at UChicago, Harvard, Stony Brook, and Quantinuum demonstrated that braiding and fusing non-Abelian anyons can perform all operations needed for universal quantum computing. This approach offers potential advantages for quantum error correction by avoiding the resource-intensive magic state distillation process typically required in standard quantum computers.
Researchers demonstrated that non-Abelian anyons can perform universal quantum computing operations using Quantinuum's H2 processor with 54 qubits. By combining braiding and fusion techniques, they showed this approach could provide quantum error correction without expensive magic state distillation, offering a more efficient path to reliable quantum computers.
