The AI Grid discusses reported US policy initiativesGovernance sets responsibilities, rules and oversight for decisions about how AI systems are used. for quantum computingQuantum computing processes information using quantum states, represented by qubits, and operations that use effects such as superposition and interference. It offers different methods for particular computational problems. and post-quantum cryptographyPost-quantum cryptography develops cryptographic methods intended to resist attacks by both classical and sufficiently capable quantum computers. These methods can run on conventional computing systems.. The presenter explains fault tolerance and describes the challenge of building machines that can correct errors while performing useful calculations.
The episode considers the potential vulnerability of some current encryption to sufficiently capable quantum computers, including the risk that encrypted data collected today could be decrypted later. It discusses a proposed transition to post-quantum protection.
The presenter describes public and private investment, strategic competition and the debate over whether a 2028 target is realistic. Timelines and market implications are presented as claims and forecasts from the episode.
