Current #quantum computers like Google's #Willow with 105 #qubits are far from the millions needed to break Bitcoin's #cryptographic security. However, future advancements could pose a threat.

**Additional Information:**
- Bitcoin uses ECDSA for transaction signatures and SHA-256 for mining, both of which could theoretically be compromised by quantum computers with millions of logical qubits.
- There are ongoing efforts to develop quantum-resistant cryptography for blockchain systems.
- Posts on X reflect concerns about quantum computing potentially unlocking Bitcoin wallets quickly, but these claims are speculative given current technology.
