Cryptography and Quantum Computing |
---|
Background: Federal agencies and critical infrastructure owners and operators rely on cryptography (e.g., encryption and decryption) to secure sensitive and personally identifiable information. Quantum computing poses significant risks to the security of this information. Most notably, a quantum computer of sufficient size and sophistication-also known as a cryptographically relevant quantum computer (CRQC)-could break many current cryptography systems used on digital systems across the United States and around the world. While a CRQC may not exist for another 10-20 years, sensitive data encrypted with current cryptography can be acquired now and saved for future decryption by CRQCs. Efforts to develop a quantum workforce may help mitigate threats that CRQCs pose and position the US as a leader in quantum. For example, as the development of quantum computers advances, workforce needs may shift from quantum physicists, to engineers, to manufacturing technicians. This engagement is part of a body of work on CRQCs.
Key Questions: 1) To what extent is the federal government complying with the National Quantum Initiative Act to develop a quantum computer capable of breaking encryption? 2) To what extent do federal actions to grow and strengthen the quantum workforce align with those identified in the Quantum Information Science and Technology Workforce Development National Strategic Plan?
