Code to accompany All entangled states can demonstrate non-classical teleportation

This repository provides a (very) small collection of code which implements the semidefinite program presented in the article
All Entangled States can Demonstrate Nonclassical Teleportation.

Phys. Rev. Lett. 119, 110501 (2017)

All code is written in MATLAB and requires:

• CVX - a Matlab-based convex modeling framework
• QETLAB - A MATLAB Toolbox for Quantum Entanglement

It has been tested on Matlab R2016b, and CVX 2.1

The code comprises the following:

• genTeleportationData: generates the unnormalised states prepared for Bob, when Alice performs a joint measurement on the (unknown) input state and her half of a shared state.
• teleportationRandomRobustness: calculates the random teleportation robustness of a given set of teleportation data.
