TL;DR: It is shown that the requirements for obtaining secure keys are much easier to meet than for DI-QKD, which opens promising experimental opportunities and clarifies the link between the security of this one-sided DI- QKD scenario and the demonstration of quantum steering, in analogy to the links between DI-ZKD and the violation of Bell inequalities.

TL;DR: In this article, the authors examined the field of the EPR gedanken experiment, from the original paper of Einstein, Podolsky, and Rosen, through to modern theoretical proposals of how to realize both the continuous-variable and discrete versions of EPR paradox.

TL;DR: In this article, the authors formally link the concept of steering (a concept created by Schrodinger but only recently formalized by Wiseman, Jones and Doherty Phys. Rev. Lett. 98 140402 (2007)]) and the criteria for demonstrations of the EPR paradox introduced by Reid Phys.

TL;DR: In this article, the authors use entropic uncertainty relations to formulate inequalities that witness EPR steering correlations in diverse quantum systems and then use these inequalities to formulate symmetric EPR-steering inequalities using the mutual information.

TL;DR: In this article, the authors derived arbitrarily loss-tolerant tests, enabling them to perform a detection-loophole-free demonstration of Einstein-Podolsky-Rosen steering with parties separated by a coiled 1-km-long optical fiber, with a total loss of 8.9 dB.
