IonQ Estimates Quantum Computer Could Decrypt Bitcoin in Weeks

Quantum computing company IonQ has published an estimate suggesting a fault-tolerant quantum computer with approximately 20,000 physical qubits could break Bitcoin's elliptic-curve cryptography in 25.7 days. IonQ's CEO forecasts "Q-Day" for Bitcoin's security as early as 2028. This highlights a growing quantum threat to current cryptographic standards, posing significant implications for digital security.
