Implications of Quantum Information Processing On Military Operations
This paper discusses the benefits and drawbacks of quantum computing and quantum cryptography, subsets of the field of Quantum Information Processing (QIP). This field uses quantum mechanics for information processing rather than classical mechanics and portends game-changing implications to technologies long-relied on by military organizations, including computing, communication, and cryptographic systems. Quantum information processing may provide advantageous to Army operations in two areas: massive parallel processing and secure key distribution.
Quantum mechanics allows a single quantum computer to compute as dozens or even hundreds of classical computers, known as ‘quantum parallelism.’ This is leading to a new paradigm in computing as these computers undermine current cryptographic systems. Continuing work in other families of cryptographic systems shows promise for being unaffected by quantum processing and quantum mechanics allows for the creation and distribution of completely secret keys. This solution may require fielding a new generation of cryptographic hardware systems throughout the Army. Quantum parallelism applies to data searching, providing a polynomial speed-up for searching large databases, such as cloud storage, personnel systems, or intelligence repositories.
“If a quantum computer is ever built, much of conventional cryptography will fall apart!” (Giles Brassard, 1984)
