Quantum computers can efficiently factor large numbers, which means that most of the current public-key cryptography is insecure against an adversary with a quantum computer.
量子计算机可以高效地分解大数，这意味着当前大多数公钥加密在量子计算机的对手面前是不安全的。
The truth is, we are all waiting for something to happen, even when we don't know what it is.
