标题： Cryptography in a Quantum World

摘要： 虽然作为一种艺术和科学已有很长的历史，但密码学直到二十世纪中叶才由克劳德·香农为其提供了坚实的数学基础。 然而，香农的方法植根于他自己的信息理论，而这一理论本身又受到牛顿和爱因斯坦的经典物理的启发。 但我们的世界是由量子力学的规律所支配的。 当考虑到量子力学现象时，密码制造者和破译者都迎来了新的前景。 量子力学对隐私保护是福音还是诅咒？ 正如我们将看到的，目前尚无定论！ 显示英文摘要

摘要： Although practised as an art and science for ages, cryptography had to wait until the mid-twentieth century before Claude Shannon gave it a strong mathematical foundation. However, Shannon's approach was rooted is his own information theory, itself inspired by the classical physics of Newton and Einstein. But our world is ruled by the laws of quantum mechanics. When quantum-mechanical phenomena are taken into account, new vistas open up both for codemakers and codebreakers. Is quantum mechanics a blessing or a curse for the protection of privacy? As we shall see, the jury is still out!
