Btc vs quantum computing

Will the rise of quantum computing undermine Bitcoin's cryptographic security, or can Bitcoin adapt with quantum-resistant technologies before quantum computers become a real threat?

IBM is already working on, and making progress with, a 400-qubit quantum processor.

Theoretical speaking only 512 qubits are required to perform Lamport signatures. Could this threat be avoided by starting preparations now?

Could quantum computing actually become a threat in the next 10-20 years? It seems more likely every day
