- 1Bitcoin Quantum Attack Estimate Halved to 1,151 Qubits▼Bitcoin Quantum Attack Cost Halved to 1,151 Qubits [2026]
New research suggests breaking Bitcoin's cryptography could require as few as 1,151 logical qubits, roughly half the previously estimated cost of a quantum attack. The revised figure intensifies debate over how soon quantum computers could threaten Bitcoin's elliptic curve signatures and whether the network should migrate to quantum-resistant cryptography before it is too late.

Physicists at the City College of New York report converting microwave signals into light using atomically thin 2D magnetic materials, a step toward connecting quantum devices. The advance could let distant quantum processors or sensors communicate through optical fiber, which transmits photons far more efficiently than microwaves. Researchers describe the work as a building block for future quantum networks.
