Summary
Quantum computing is moving from theory toward early practical use, with direct implications for encryption, authentication, and long-term data confidentiality.
The primary risk is the eventual emergence of cryptographically relevant quantum computers (CRQCs), which would break today’s public-key cryptography and undermine encryption, digital identity, and software trust at scale.
Quantum risk is already present: “harvest now, decrypt later” activit
