Welcome to the Quantum News Daily Brief. Story 1: Walking Floquet code circuits for zero-overhead leakage reduction. To address this challenge, we introduce two zero-overhead walking circuits for the honeycomb Floquet code (hFC), termed the swirling and sliding circuits, which periodically remove leakage while dynamically protecting logical qubits via a schedule of anticommuting two-body measurements. We further study their performance under leakage and find that, for two leakage noise models, t

Welcome to the Quantum News Daily Brief. Story 1: Quantum agents can reason consistently, new framework shows. V. Vilasini and Mischa P. Woods, affiliated with ETH Zurich and Université Grenoble Alpes, have developed a general quantum circuit framework addressing a longstanding question in quantum physics: can reasoning remain logically consistent when quantum theory is applied universally? Their work demonstrates these can be resolved by explicitly accounting for quantum channels used in the re

Welcome to the Quantum News Daily Brief. Story 1: The Qubit Report: September 8, 2026. Washington is no longer only writing research checks. Equity, foundry slots, and 2027 delivery dates now sit on the same page as helium sketches and a 25.7-day paper attack on a 256-bit curve. The industrial story is capacity and control. The lab story is still prototypes and resource estimates. Treat both as progress. Treat neither as a finished machine. Treat yourself to a snapshot of today's quantum news. T

Welcome to the Quantum News Daily Brief. Story 1: ‘Shape-shifting’ quantum computer uses light to switch between different tasks - The Brighter Side of News. The system demonstrated 100-mode Gaussian boson sampling, quantum correlations across 8,000 time bins, Schrödinger cat states and quasi-deterministic production of error-correction resources called GKP states at roughly 2,000 per second.
