Bitcoin quantum threat is real and closer than it looks, says Nobel physicist

Nobel laureate Dr. John Martinis warns that quantum computing advancements could soon threaten Bitcoin's elliptic curve cryptography, requiring urgent industry planning.Summary
Dr. John Martinis, a Nobel Prize-winning physicist and former Google quantum hardware leader, warns that Bitcoin faces a genuine threat from quantum computing. He argues that the network's reliance on elliptic curve cryptography makes it a prime target, as quantum machines could theoretically derive private keys from public keys during the transaction broadcast window. While Martinis acknowledges that building a sufficiently powerful quantum computer remains a significant engineering hurdle, he emphasizes that the crypto community must begin planning for a quantum-resistant transition now to mitigate future risks.
