Work that took 1 hour now done in 15 seconds as quantum advances raise Q-Day concerns

Quantum computing has returned to the forefront of market attention over its potential impact on blockchain security after bitcoin slipped to around $63,000. AT&T expanded its contract with D-Wave Quantum and integrated quantum annealing into network optimisation algorithms, saying tasks that took 1 hour can now be completed in 15 seconds. The development coincided with weakness in cryptocurrencies and forced liquidations, while executives and researchers flagged faster timelines for quantum threats to cryptography.

U.S. power grid key equipment \'transformer\' in short supply; import reliance 80 percent, lead times up to 5 years

The U.S. hydropower industry is struggling to replace and upgrade equipment due to difficulties procuring large power transformers, a report said. The analysis by the National Renewable Energy Laboratory identified nine key issues, including about 80 percent import reliance for critical raw materials and limited global capacity for ultra-high-voltage transformers. Lead times range from 2.5 to 3 years and can reach 5 years, while prices have risen about 80 percent since 2021.

Transformer shortage pushes lead times to up to 4 years as AI data centre, EV demand surges

Europe and North American power grids could see new power connections delayed for years due to shortages of power transformers, a key piece of equipment. Demand is rising as AI data centres, electric vehicles and industrial electrification expand. Lead times that were typically 6 to 12 months before 2020 now run 24 to 48 months, with large units taking more than 36 months. Prices are up 50 to 80 percent, while material, labour and testing constraints limit supply.
