According to the Anhui Province Key Laboratory of Quantum Computing Chips, a joint research team from Origin Quantum and the University of Science and Technology of China has innovatively proposed a "parameter-space-extended controlled-phase gate (PSE-CZ)" scheme, successfully resolving the long-standing trade-off between speed and fidelity in superconducting quantum computing, and achieving a two-qubit quantum gate that significantly enhances accuracy while maintaining high-speed operation. The results have been published in Physical Review Letters, a top international physics journal, with experimental verification carried out on China's independently developed superconducting quantum computer "Origin Wukong".

【Flash | ESAB Cuts Q4 Surcharges for Mo-Bearing Welding Consumables】

ESAB published its Q4 2026 US combined alloy-and-tariff surcharges for welding filler metals. The surcharge for 316/316L stainless solid wire fell from $7.08/lb ($15.57/kg) in Q3 to $6.26/lb ($13.77/kg), while 317/317L declined to $6.72/lb. Duplex 2209 and super-duplex 2509/2594/2507 eased to $8.71/lb and $9.02/lb. ERNiCrMo-3 nickel-alloy solid wire fell from $15.53/lb to $13.28/lb. SMM analysis: Mo-bearing welding-consumable surcharges broadly declined QoQ, but the combined charges also reflect nickel, chromium and tariff costs and are not molybdenum spot prices.
