TL;DR: The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) as discussed by the authors is a special reflecting Schmidt telescope with an innovative active reflecting Schmidt configuration which continuously changes the mirror's surface that adjusts during the observation process and combines thin deformable mirror active optics with segmented active optics.

TL;DR: The Large sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) general survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and collect 10 million spectra of stars, galaxies and QSOs as discussed by the authors.

TL;DR: Up-conversion single-photon detectors with high efficiency and low noise are developed to faithfully demonstrate the measurement-device-independent quantum-key-distribution protocol, which is immune to all hacking strategies on detection and employed to defend attacks on a nonideal source.

TL;DR: In this article, a bias-free quantum random number generator (QRNG) using photon arrival time selectively, in accordance with the number of photon detection events within a sampling time interval in attenuated light, is presented.

TL;DR: A 75 MHz clock rate fully automatic and highly stable system and superconducting nanowire single-photon detectors with detection efficiencies of more than 40%, which extends the secure transmission distance of MDIQKD to 200 km and achieves a secure key rate 3 orders of magnitude higher.
