US Bans Chinese Tech in Cars, Sweden's 100,000 Year Nuclear Waste Plan, and Schrödinger's Cat Quantum Breakthrough

The Biden administration has finalized regulations banning Chinese and Russian software and hardware in connected vehicles, effective January 2025, due to national security concerns. These regulations specifically target vehicle connectivity and automated driving systems in passenger vehicles under £10,000, with a software ban for model year 2027 and a hardware ban for model year 2030. The focus is on components that could be exploited for data collection and remote manipulation.

In Sweden, construction has begun on a deep geologic repository for spent nuclear fuel at Forsmark, designed to safely store highly radioactive waste for 100,000 years. Located 500 meters underground in ancient bedrock, the facility will hold over 12,000 tons of spent fuel in copper canisters surrounded by bentonite clay. This project is a significant milestone in nuclear waste management, making Sweden the second country after Finland to establish a permanent storage solution, with the repository expected to be operational by 2080.

Researchers at the University of New South Wales have achieved a breakthrough in quantum computing by creating a Schrödinger's cat state within a silicon chip. This advancement enhances error correction capabilities, addressing a critical challenge in developing functional quantum computers. By utilizing an antimony atom to generate a quantum state with eight distinct spin directions, the researchers have developed a more resilient architecture compared to traditional qubits, improving stability and enabling sophisticated error correction protocols. Future research will focus on scaling this technology and developing specialized algorithms for practical applications.
