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.

TL;DR: An automatic feedback MDIQKD system operated at a high clock rate is developed, and a field test via deployed fiber network of 30 km total length achieving a 16.9 b/s secure key rate lays the foundation for a global quantum network, which can shield from all the detection-side attacks.

TL;DR: In this paper, an automatic feedback measurement-device-independent QKD (MDIQKD) system operated at a high clock rate, achieving a 16.9 bps secure key rate.

TL;DR: The design structure could be used in many high-precision detector systems as infrared detector or high-energy particles detectors, and the system has been tested in an extreme environment as low as 193 K.
