Quantum teleportation is one of the fundamental building blocks of quantum Shannon theory. While ordinary teleportation is simple and efficient, port-based teleportation (PBT) enables applications such as universal programmable quantum processors, instantaneous non-local quantum computation and attacks on position-based quantum cryptography. In this work, we determine the fundamental limit on the performance of PBT: for arbitrary fixed input dimension and a large number N of ports, the error of…
Multiport based teleportation -- protocol and its performance
• Computer Science
• 2020
A lower bound on the performance of the protocol, measured in the entanglement fidelity, is derived using equivalence between the teleportation process and state discrimination task and it is obtained that maximal number of faithfully teleported systems differs qualitatively in deterministic and probabilistic scheme.
Optimality of the pretty good measurement for port-based teleportation
This paper gives an explicit proof that the so-called pretty good measurement, or square-root measurement, is optimal for the PBT protocol with independent copies of maximally entangled states as the port state, and shows that the very same measurement remains optimal even when theport state is optimized to yield the best possible P BT protocol.

The obtained bound is effectively computable and outperforms the explicit values of the entanglement fidelity calculated for the pre-existing variants of the port-based protocols, allowing for teleportation of a much larger amount of quantum information.
Square-root measurements and degradation of the resource state in port-based teleportation scheme

This paper analyzes for the first time the recycling protocol for the deterministic PBT beyond the qubit case and presents the explicit formula for the recycling fidelity involving only group-theoretic parameters describing irreducible representations in the Schur-Weyl duality.
Minimal Port-based Teleportation
• Computer Science
• 2021
The minimal set of requirements that define a feasible P BT protocol are introduced and a simple PBT protocol is constructed that satisfies these requirements: it teleports an unknown state of a qubit with success probability psucc = 1− N+2 2N+1 and fidelity 1−O( 1 N ) with the resource state consisting of N maximally entangled states.
Optimization and learning of quantum programs
• Computer Science
• 2019
This work proves that the search for the optimal quantum program is a convex optimization problem, and applies this general result to a number of different designs for the programmable quantum processor, from the shallow protocol of quantum teleportation, to deeper schemes relying on port-based teleportation and parametric quantum circuits.

A graph-theoretic algebra is constructed which allows us to explicitly compute the higher-dimensional performance of PBT for so-called “pretty-good measurements” with negligible representational overhead and shows that the entanglement fidelity asymptotically approaches N/d2 for large d, confirming the performance of one lower bound from the literature.

It is demonstrated that a scheme of quantum teleportation where a receiver has multiple output ports and obtains the teleported state by merely selecting one of the N ports according to the outcome of the sender's measurement is possible by showing an explicit protocol where N pairs of maximally entangled qubits are employed.
Popescu-Rohrlich correlations imply efficient instantaneous nonlocal quantum computation
A linear amount of entanglement suffices, (in the size of the computation), as long as the parties share nonlocal correlations as given by the Popescu-Rohrlich box, which implies the impossibility of secure position-based cryptography against adversaries with nonsignaling correlations.
