NSA Releases Quantum Computing, Post-Quantum Cryptography FAQs

The National Security Agency is a national-level intelligence agency of the United States Department of Defense, under the authority of the Director of National Intelligence. NSA views quantum-resistant (or post-quantum) cryptography as a more cost effective and easily maintained solution than quantum key distribution. For all of these reasons, NSA does not support the usage of QKD or QC to protect communications in National Security Systems, and does not anticipate certifying or approving any QKD or QC security products for usage by NSS customers unless these limitations are overcome. The Laboratory for Physical Sciences (LPS) at the National Security Agency is deeply engaged in Quantum Information Science (QIS) R&D, covering quantum computing, sensing, and communications, along with supporting technologies. Their programs include Quantum Computing in the Solid State (QC-5), Stable High Fidelity Trapped Ion Systems, and Quantum Characterization of Intermediate-Scale Systems. LPS collaborates with partners like the Army Research Office (ARO) to advance initiatives like QC-5, focusing on various aspects of qubit research. Through the Quantum Computing Fund (QCF), LPS facilitates access to advanced qubits for research groups. Established in 2020, the Laboratory for Quantum Computing (LQC) supports the National Quantum Initiative (NQI) Act, promoting collaboration across government, industry, and academia. LQC's "Super Semi Lab" is a dedicated facility for quantum materials and qubit research. Additionally, LPS conducts quantum sensing research to develop highly sensitive magnetometers for national security applications.
