Nvidia tests technique to cut physical qubits needed for error correction by 90 percent

Nvidia carried out a 104-qubit quantum computing simulation on Germany’s Jupiter, Europe’s first exascale supercomputer, and tested a technique that could cut the physical-qubit resources required for error correction by 90 percent. The study focused on efficiently preparing magic states through Magic State Cultivation under noise conditions close to real quantum hardware. Nvidia used GH200-based systems and scaled workloads to 8,192 GPUs, with cuQuantum and CUDA-Q software platforms.

Ethereum quantum-resistance direction takes shape as Buterin and Zcash co-founder align

As debate grows over Ethereum’s shift to quantum-resistant cryptography, Vitalik Buterin (비탈릭 부테린) and Zcash co-founder Eli Ben-Sasson (엘리 벤사손) have backed a hash-based approach. The emerging concept is to design the core consensus around hash-based signatures and proof aggregation, while allowing lattice cryptography at the account and wallet layer if its security is proven. The discussion was sparked after a16z crypto questioned reliance on recursive SNARK structures.

Claude finds quantum computation method in 53 hours, cuts operations to one-seventeenth

Anthropic\'s AI model Claude autonomously designed eight types of quantum computing procedures and reduced required qubits and operation counts in seven of them compared with existing optimal designs. Some designs improved resource efficiency by more than 10 times. The work focused on point addition used repeatedly in elliptic-curve cryptography, which underpins transaction signatures for Bitcoin and Ethereum. Anthropic said it did not attack cryptocurrencies or estimate the total quantum computer size needed to break them.
