Welcome to the Quantum News Daily Brief. Story 1: Fault-Tolerant Heisenberg-Limited Quantum Sensing. For this noise structure, we demonstrate that, given a total sensing time $T$, Heisenberg scaling can be attained for times up to $T\propto 1/p^{(N+1)/2}$ for a $N$-qubit repetition code, in contrast with $T\propto 1/p$ without using a fault-tolerant sensing protocol. --> Quantum Physics arXiv:2608.00171 (quant-ph) [Submitted on 31 Jul 2026] Title:Fault-Tolerant Heisenberg-Limited Quantum Sensing

Welcome to the Quantum News Daily Brief. Story 1: Quantum Computing’s “Dark Horse” Just Cleared a Major Hurdle. Researchers have shown that exotic quantum objects called non-Abelian anyons can support a complete set of operations for universal quantum computing. Credit: ShutterstockResearchers demonstrated that braiding and fusing particles known as non-Abelian anyons can perform every operation required by a quantum computer. Researchers from the University of Chicago Pritzker School of Molecul

Welcome to the Quantum News Daily Brief. Story 1: Prefix-Suffix System Achieves Perfect Fidelity on 13-Node Quantum Network. A numerical example, conducted on a 13-node network, demonstrates that the proposed hierarchical encoding scheme is feasible and achieves perfect fidelity, demonstrating negligible recovery and isometry errors. Dick Maryopi, as first author, proposes a lossless source coding scheme for addressing in quantum networks that enables compact and coherently processable quantum a
