Members of the House Science Committee pressed witnesses on national security implications of quantum computing and on timelines for migrating to post-quantum cryptography (PQC).
Pete Shadbolt of PsiQuantum told the committee that it is "pretty clear" large-scale quantum computers can be built and that those systems would threaten current public-key encryption such as RSA and elliptic-curve cryptography.
