On March 25, Google released a blog post titled “Quantum frontiers may be closer than they appear.” Here’s how it begins: “Google’s introducing a 2029 timeline to secure the quantum era with post-quantum cryptography (PQC) migration. “Last month, we called to secure the quantum era before a future quantum computer can break current encryption. This new timeline reflects migration needs for the PQC era in light of progress on quantum computing hardware development, quantum error correction and quantum factoring resource estimates.” In a related and more detailed Google blog on the topic of safeguarding cryptocurrencies that was released on March 31, they elaborated: “Google has led the responsible transition to post-quantum cryptography since 2016. In a new whitepaper, we show that future quantum computers may break the elliptic curve cryptography that protects cryptocurrency and other systems with fewer qubits and gates than previously realized.
