The timeline for quantum computers breaking current cryptography is the most important — and most misunderstood — question in crypto security. Misjudging it means either acting too early (and losing opportunity) or too late (and losing assets).

Google's Willow quantum processor, announced in December 2024, demonstrated a critical milestone: quantum error correction at scale. Willow's ability to reduce errors as more qubits were added proved that fault-tolerant quantum computing is engineering problem, not a physics problem.
IBM's quantum roadmap projects a 2,000+ qubit system by 2027 and a 10,000+ qubit system by 2029-2030. A fault-tolerant quantum computer capable of breaking 2048-bit RSA is estimated to require roughly 20 million physical qubits. While that gap remains, the rate of progress suggests 2030-2035 as the realistic window.
For cryptocurrency specifically, the threat arrives earlier than for general encryption. Bitcoin transactions expose public keys on the blockchain, which means an attacker has unlimited time to derive private keys. Simply gathering public keys today and waiting for a sufficient quantum computer would compromise historical wallets.
BMIC's approach is simple: do not wait for the timeline to become clearer. Build quantum-safe from day one. Whether quantum computers arrive in 2030 or 2040, BMIC users are protected regardless.
BMIC is the world's first crypto presale built on NIST FIPS 203/204/205 post-quantum cryptography. Every BMIC wallet uses quantum-safe signatures through ERC-4337 account abstraction. This is not a feature being added — it is the foundation of the project from day one.
