TL;DR: In this paper, the authors describe a miniaturized, polarization entangled, photon-pair source operating on board a nano-satellite, which violates Bell's inequality with a Clauser-Horne-Shimony-Holt parameter of 2.60±0.06.

TL;DR: In this article, a constellation model is described which enables QKD-derived encryption keys to be established between any two ground stations with low latency, which is achieved through the use of low earth orbit trusted-node Q-KD satellites which create a buffer of keys with the ground stations they pass over, and geostationary relay satellites to transfer secure combinations of the keys to ground stations.

TL;DR: This Letter describes a miniaturized, polarization entangled, photon-pair source operating on board a nano-satellite that violates Bell’s inequality with a Clauser–Horne–Shimony–Holt parameter of 2.60±0.06.

TL;DR: In this article, a high-level summary of advancements in satellite-QKD is provided by analyzing past, present and proposed satellite QKD missions and initiatives around the world.

TL;DR: It is argued that for free-space quantum communications, especially with satellites, if one assumes that man-in-the-middle attacks can be detected by classical channel monitoring techniques, simplified quantum communications protocols and hardware systems can be implemented that offer improved key rates.
