Construction Begins at 1M Qubit Quantum Facility

Quantum computing company PsiQuantum has broken ground on a 1 million-qubit quantum facility in Chicago, a scale that experts suggest is powerful enough to break Bitcoin's cryptography. Co-founder Peter Shadbolt shared progress on the construction, which is being built in collaboration with Nvidia and aims to house quantum computers capable of handling errors to support next-generation AI supercomputers. The potential threat of quantum computers to Bitcoin's security, which secures $1.4 trillion, has caused debate, with some developers discussing potential hard forks for quantum resistance. While estimates vary, some research suggests around 100,000 qubits could break 2048-bit keys, though Bitcoin uses 256-bit keys. PsiQuantum has publicly stated it has no intention of using its quantum computers to attack Bitcoin private keys. Furthermore, research from CoinShares suggests that only about 10,230 BTC are currently in quantum-vulnerable addresses with publicly visible keys.
