TL;DR: In this article, the first field test of quantum teleportation is implemented over a 30 km optical fiber network with independent quantum light sources, and several feedback mechanisms are developed to establish a robust quantum teleportation system in the real world.

TL;DR: In this article, the authors used state-of-the-art quantum optical technology to create, modulate and detect entangled photon pairs, achieving an efficiency of more than 78 per cent from creation to detection at a distance of about 200 metres that greatly exceeds the threshold for closing the "detection" loophole of the Bell test.

TL;DR: A test that achieves an efficiency greater than (78%)^{2} for entangled photon pairs separated by 183 m, and an upper bound on the p value clearly indicates the rejection with high confidence of potential local hidden variable models.

TL;DR: In this paper, the authors reported the experimental realization of a ten-photon Greenberger-Horne-Zeilinger state using thin BiB3O6 crystals, demonstrating a genuine entanglement with a standard deviation of 3.6σ.

TL;DR: This work demonstrates device-independent quantum randomness generation from a loophole-free Bell test with a more efficient quantum-proof protocol, obtaining multiple blocks of 512 random bits with an average experiment time of less than 5 min per block and with a certified error bounded by 2^{-64}≈5.42×10^{-20}.
