Physical vs Logical Qubits and Fidelity

Join Tommy Shaughnessy as he speaks with Nic Carter, partner at Castle Island Ventures, about his deep dive into the existential threat quantum computing poses to Bitcoin. After six months of intensive research and discussions with Nobel Prize-winning physicists, Nic breaks down why the "quantum threat" has moved from theoretical FUD to a material risk that the Bitcoin community is currently unprepared to face.They explore the "Q-Day" timeline, the vulnerability of Satoshi’s 2 million BTC, and the urgent need for a migration to post-quantum cryptography. Can Bitcoin’s rigid governance survive the most significant technical challenge in its history, or will sovereign nations and private firms reach the coins first?🎯 Key Highlights▸Why Nic stepped away from podcasts and TV to focus on precise technical writing.▸The 2025 Quantum Inflection: Why 2025 was a record year for quantum investment.▸The Trillion Dollar Bug Bounty: The "unsolvable" problem of Satoshi’s P2PK addresses.▸Why Bitcoin developers implemented Taproot without making it quantum-resistant.▸Defense in Depth for BTC: The technical hurdles of implementing post-quantum signature schemes and the potential for a mandatory "migration" period.▸How the U.S.–China rivalry mirrors the 1939 race for the atomic bomb.▸Applying maritime law to the potential "theft" of ancient Bitcoins by private firms like IBM or Microsoft.▸Scoring the Bitcoin core developers’ preparedness at a 1/100.💡 Want to stay updated with the latest in crypto & AI?
