The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
NVIDIA's[2][6] newsroom dates the release 'September 14, 2026' ('NVIDIA today announced'), and SiliconANGLE's[4] report stamped 09:00 EDT that day says 'The announcement came at this week's IEEE Quantum Week 2026 event that kicked off in Toronto today.'
NVIDIA's[1][6] event page: IEEE Quantum Week 2026 runs 'September 13–18, Toronto, Canada' at the Metro Toronto Convention Centre, with an NVIDIA booth, tutorials and a keynote by Krysta Svore on the fault-tolerant era.
Trade analysis stating 'At IEEE Quantum Week 2026 in Toronto, NVIDIA[1][2][6] announced' CUDA-Q Logical, and describing how it lowers logical programs to QEC microcode, pulse schedules and real-time control plans and derives resource estimates from compiler artifacts.
Same-day report (09:00 EDT, September 14, 2026) that places the launch: 'The announcement came at this week's IEEE Quantum Week 2026 event that kicked off in Toronto today', and restates the Iceberg Quantum/Diraq and Fermilab results.[1]
Infleqtion's own release of September 14, 2026 (NYSE: INFQ): working with an early-access CUDA-Q Logical and its qLDPC library it validated a high-rate code using about six physical data qubits per logical qubit, about a fivefold code-rate gain over a surface-code comparison; it presents at IEEE Quantum Week in Toronto that week.
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
