WebMar 21, 2024 · Quantum encryption relies on the fact that eavesdropping—trying to gain information on a message—is a form of measurement and will disturb a system in a way that can be detected. Now the amount of disturbance is very small—proportional to Planck’s constant, one of the smallest quantities in physics. But if you use very small objects, or ... WebRSA encryption relies on the fact that multiplication of large primes is easy and thus fast, but factoring large composite numbers into two prime factors is very difficult and thus slow.
