Optimization and learning of quantum programs
TL;DR: 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.

TL;DR: In this article, a more careful analysis confirms that indeed there is no paradox, contrary to his claims, and points out that Ralph has not accounted for all the interactions needed for his construction, which voids our argument that P-CTCs are able to resolve such types of paradoxes.
Journal ArticleDOI
Mixed state entanglement classification using artificial neural networks
TL;DR: In this article, the authors extend the use of SNNS to mixed, multipartite states, providing a versatile and efficient tool for the investigation of intricately entangled quantum systems.

Tight finite-resource bounds for private communication over Gaussian channels.
TL;DR: It is shown how a class of finite-energy resource states are able to increasingly approximate the infinite-energy bounds for decreasing purity, so that they provide tight upper bounds to the secret-key capacity of one-mode phase-insensitive Gaussian channels.

Composably secure data processing for Gaussian-modulated continuous variable quantum key distribution
TL;DR: In this article, a Gaussian-modulated coherent-state protocol with homodyne detection in the general setting of composable finite-size security is considered, and the output classical data is post-processed via procedures of parameter estimation, error correction, and privacy amplification.
