While it can be used for all kinds of good, quantum computing could also be used to unravel critical systems.One of the most common ways to protect data is to encrypt it using an RSA algorithm. In simple terms, it relies on the fact that while you can easily multiply one prime number by another, it’s very hard to work out prime factors from any given number. Quantum computing could make this much easier, allowing cr...
