The Unexpected Link Between Quantum Advantage and Cryptography
Quantum computing promises exponential speedups for certain problems, but when does this quantum advantage actually exist? A ground-breaking study from Kyoto University reveals a deep connection: Quantum advantage exists if and only if certain cryptographic puzzles are secure. This discovery bridges quantum computing and cryptography, reshaping our understanding of both fields—and potentially destabilizing cryptosystems previously thought to be safe. What Is Quantum Advantage? Quantum computers…
