The paper discusses teleportation in the context of comparing quantum and topological points of view.

Quantum key distribution is the most well-known application of quantum cryptography. Previous proposed proofs of security of quantum key distribution contain various technical subtleties. Here, a conceptually simpler proof of security of quantum key distribution is presented. The new insight is the invariance of the error rate of a teleportation channel: We show that the error rate of a telepor...

In Higher Quantum Theory [2], Vicary outlines a generalisation of the usual quantum teleportation protocol, based on the idea of interlacing two separate teleportation procedures. We show here that the protocol he specifies is impossible to implement with qubits. 1 Background An appealing strength of categorical quantum mechanics, initiated by Abramsky and Coecke [1], is that the categorical fr...

Abstract In this review, we present the ongoing developments in bridging gap between holography and experiments. To end, discuss information scrambling models of quantum teleportation via Gao–Jafferis–Wall wormhole teleportation. We review essential basics summarize some recent works that have so far been obtained simulators towards a goal realizing analogous lab.

We derive the maximum fidelity attainable for teleportation using a shared pair of d-level systems in an arbitrary pure state. This derivation provides a complete set of necessary and sufficient conditions for optimal teleportation protocols. We also discuss the information on the teleported particle which is revealed in course of the protocol using a non-maximally entangled state. PACS numbers...
