Quantum Computing and Cybersecurity Threat Assessment

This technical report discusses the current state of quantum computing and its implications for cybersecurity threats. It outlines the potential risks posed by quantum computers to asymmetric cryptographic protocols, particularly the RSA encryption method, which secures classified and sensitive data. The report emphasizes the importance of monitoring advancements in quantum computing technology, particularly in relation to national security. It introduces the concept of quantum volume as a metric for assessing quantum computing power and predicts that a quantum computer capable of breaking RSA-2048 may not be available for several decades. The report also highlights the competitive landscape, noting that while the U.S. leads in quantum computing, other nations, particularly China, are making significant strides in related technologies. Recommendations for the Intelligence Community include developing post-quantum cryptography strategies to mitigate the risks associated with quantum computing advancements.
