Computable bounds for the discrimination of Gaussian states
Stefano Pirandola,Seth Lloyd +1 more
TL;DR: By combining the Minkowski inequality and the quantum Chernoff bound, easy-to-compute upper bounds for the error probability affecting the optimal discrimination of Gaussian states are derived.
Journal ArticleDOI
Quantum cryptography approaching the classical limit
TL;DR: In this article, the authors consider the security of continuous variable quantum cryptography at wavelengths considerably longer than optical and find that regions of security still exist all the way down to the microwave.
Journal ArticleDOI
Closed timelike curves via postselection: theory and experimental test of consistency
Seth Lloyd,Lorenzo Maccone,Raúl García-Patrón,Vittorio Giovannetti,Yutaka Shikano,Yutaka Shikano,Stefano Pirandola,Lee A. Rozema,Ardavan Darabi,Yasaman Soudagar,Lynden K. Shalm,Aephraim M. Steinberg +11 more
TL;DR: In this paper, an alternative quantum formulation of closed timelike curves based on teleportation and postselection was proposed, and it is shown that it is inequivalent to Deutsch's theory.
Journal ArticleDOI
Theory of channel simulation and bounds for private communication
Stefano Pirandola,Samuel L. Braunstein,Riccardo Laurenza,Carlo Ottaviani,Thomas P. W. Cope,Gaetana Spedalieri,Gaetana Spedalieri,Leonardo Banchi,Leonardo Banchi +8 more
TL;DR: In this article, a general weak converse bound for private communication based on the relative entropy of entanglement is proposed, and the authors provide a rigorous proof of the strong converse property of these bounds by adopting a correct use of the Braunstein-Kimble teleportation protocol for the simulation of bosonic Gaussian channels.

Capacities of repeater-assisted quantum communications
TL;DR: This work derives single-letter upper bounds for the end-to-end capacities in repeater chains and quantum networks connected by arbitrary quantum channels, establishing exact formulas under basic decoherence models, including bosonic lossy channels, quantum-limited amplifiers, dephasing and erasure channels.
