A Computational Separation Between Quantum No-cloning and No-teleportation. (arXiv:2302.01858v1 [quant-ph])
cs.CR updates on arXiv.org arxiv.org
Two of the fundamental no-go theorems of quantum information are the
no-cloning theorem (that it is impossible to make copies of general quantum
states) and the no-teleportation theorem (the prohibition on sending quantum
states over classical channels without pre-shared entanglement). They are known
to be equivalent, in the sense that a collection of quantum states is clonable
if and only if it is teleportable. Our main result suggests that this is not
the case when computational efficiency is considered. We …
