New Quantum Model Cuts Hardware Needed to Break Bitcoin Keys 17-Fold

Original: New Quantum Model Cuts Estimated Hardware Needed to Break Bitcoin Keys by 17 Times Alice & Bob researchers estimate a 30

Researchers at Alice & Bob have published a new estimate suggesting a quantum computer with around 30,000 qubits could break Bitcoin's cryptographic keys in roughly an hour — about 17 times less hardware than earlier estimates assumed. The finding, based on a revised quantum error-correction model, reignites debate over how urgent it is for Bitcoin to adopt quantum-resistant cryptography and how close real-world threats may be.

Why now: Fresh research sharply lowers the estimated quantum resources needed to threaten Bitcoin, prompting renewed debate about quantum risk to crypto.
