TL;DR: In this article, the entanglement of three remote quantum memories via three-photon interference was achieved by employing laser-cooled atomic ensembles and making use of a ring cavity to enhance the overall efficiency of the memory.

TL;DR: In this paper, an InGaAs/InP single-photon detector with 1.25 GHz sine wave gating (SWG) using a monolithically integrated readout circuit (MIRC) is presented.

TL;DR: In this paper, a hybrid entanglement between three photons and three atomic-ensemble quantum memories was realized by measuring the photons and applying feedforward, and heraldedly entangling the three memories.

TL;DR: Chaves and Pienaar as discussed by the authors carried out an experiment of a device-independent delayed-choice experiment using photon states that are space-like separated, and demonstrate a loophole-free version of the delayed choice protocol that is consistent with quantum theory but inconsistent with any causal two-dimensional hidden variable theory, which salvages the thought experiment and shows that causality can be used to test quantum theory in a complementary way to the Bell and Leggett-Garg tests.

TL;DR: This work presents for the first time, to the best of its knowledge, an InGaAs/InP SPD with 1.25 GHz sine wave gating (SWG) using a monolithically integrated readout circuit (MIRC), and describes the functionality and reliability of the MIRC.
