| This new field is fascinating for at least three reasons. First, it provides a method for realizing communication and computation tasks that are classically impossible, such as distributing a secret key over a vulnerable channel or factoring a large number in polynomial time. Second, it gives a new language to understand - and new tools to analyze - the peculiarities of quantum mechanics such as entanglement and nonlocality. | This new field is fascinating for at least three reasons.
