Dolev Bluvstein, CEO of Oratomic, an atomic‑qubit quantum startup. Alex Pruden, CEO of Project Eleven, building post‑quantum wallets and migration tools. They unpack new papers that tighten the timeline for quantum threats to Bitcoin, explain Oratomic's 10,000‑qubit claim and lab progress, and outline practical migration strategies and attack windows for vulnerable on‑chain funds.

Episode notes
Responsible Disclosure For Quantum Findings
- Google used responsible-disclosure style proof to show vulnerability without publishing exploitable details.
- The paper argues revealing a small circuit proof warns defenders while avoiding enabling attackers.
Begin Migration Immediately With Practical Work
- Start migrating now: rebuild wallets, contracts and admin keys to post-quantum algorithms and test rigorously.
- Alex urges shovels-in-the-ground work: sig nets, testnets, migration tools and audited implementations.
Quantum Key Recovery Breaks Trustless Property
- Q-Day would let an attacker recover private keys from public keys, exposing lost coins like Satoshi’s and breaking trustless property.
- Alex frames recovered lost coins as a social and protocol governance problem without a centralized fix.
