A few days ago, we were discussing the quantum computing threats faced by Bitcoin and Ethereum, but today this topic has already exploded in the cryptocurrency industry. Because two heavyweight papers have just been published. First, let's talk about the key points: The speed at which quantum computers can deduce private keys from exposed public keys may be even faster than previously estimated by the industry. The mainstream view used to believe that the key nodes would occur around 2031-2038, but now the probability of early occurrence has increased, although it does not necessarily mean that it will happen. One of the papers is from Google Quantum AI (Google Quantum Team). They conducted deep optimization on the "Shor algorithm" (a quantum algorithm specifically designed to crack elliptic curve encryption), which is particularly adapted to the secp256k1 curve used by Bitcoin and Ethereum. The paper mentions that if using the superconducting quantum computer currently being developed by Google, it only takes a few minutes to recover the corresponding private key from an exposed public key. However, the machine has not yet been manufactured and is still in the stage of theoretical resource estimation.

Based on similar efficient logic layer optimization, they further combined the unique physical layer technology of neutral atom quantum computers to achieve a composite breakthrough. The paper mentions that only about 26000 physical qubits are needed to crack the secp256k1 private key, which is about 40 times less than the previous optimal solution (according to Justin Drake's evaluation). However, due to the slow running speed of neutral atom quantum computers, a complete crack takes about 10 days.

This means that previous assessments of quantum threat timelines may be somewhat conservative. It is now time to attach great importance to anti quantum encryption - the good news is that there is already a feasible technological roadmap. The probability of implementing a cryptography related quantum computer (CRQC) in the next 5 years is not high, but over time, this probability will gradually increase. At present, Ethereum has a clear post quantum roadmap and has listed it as a strategic priority; The Bitcoin community does need to take it seriously as soon as possible and plan ahead for the migration of signature algorithms.
