Quantum Computing: A Revolutionary Game Changer or a Mere Supercomputer?

Quantum computing has been a hot topic for years now, with its potential to revolutionize computing and be a game changer in various fields, including military applications. We recently had the chance to discuss the state of quantum computing with Joe Altepeter, a program manager in DARPA’s Defense Sciences Office (DSO), who manages two of DARPA’s three main quantum programs. Altepeter shared that the interest in quantum computers took off in 1995 when Peter Shor discovered an algorithm for efficiently factoring large numbers. However, when asked about the priority for the US government in terms of offensive and defensive capabilities, Altepeter stated that DARPA's mandate is to eliminate strategic surprise. They are more focused on finding the next surprising application of quantum computers that could lead to a computing revolution. The big question surrounding quantum computing is whether it will truly revolutionize computing disciplines, or if it won't be able to do anything that a classic supercomputer can't do. Altepeter mentioned that this uncertainty is what makes quantum computing an area with significant potential for strategic surprise. While some physicists believe quantum computers will completely change computing in the 21st century, others think it won't be much better than today's supercomputers. As of now, the DoD doesn't use quantum computers for real problems, but DARPA's efforts aim to bring clarity to this debate and uncover the true potential of quantum computing.
