This Sunday's think piece takes on quantum cryptography's strangest promise: uncloneable encryption, which uses the no-cloning theorem to make copying a stolen ciphertext physically impossible rather than just computationally hard. We walk four competing camps — unconditional security, efficient reusability, weakest-assumption 'microcrypt,' and the impossibility theorists keeping everyone honest — that all published within weeks of each other trying to push the primitive from a single guaranteed bit toward real, arbitrary-length messages.
