This work reports the development and launch of a low-Earth-orbit satellite for implementing decoy-state QKD—a form ofQKD that uses weak coherent pulses at high channel loss and is secure because photon-number-splitting eavesdropping can be detected.

Satellite-based distribution of entangled photon pairs to two locations separated by 1203 kilometers on Earth, through two satellite-to-ground downlinks is demonstrated, with a survival of two-photon entanglement and a violation of Bell inequality.

Gaussian boson sampling was performed by sending 50 indistinguishable single-mode squeezed states into a 100-mode ultralow-loss interferometer with full connectivity and random matrix and sampling the output using 100 high-efficiency single-photon detectors, and the obtained samples were validated against plausible hypotheses exploiting thermal states, distinguishable photons, and uniform distribution.

A new class of SQEs based on excitons that are spatially localized by defects in 2D tungsten-diselenide (WSe2) monolayers is reported, which could give rise to practical advantages in quantum-information processing, such as an efficient photon extraction and a high integratability and scalability.

The Micius satellite is confirmed as a robust platform for quantum key distribution with different ground stations on Earth, and points towards an efficient solution for an ultralong-distance global quantum network.
Experimental test of quantum nonlocality in three-photon Greenberger–Horne–Zeilinger entanglement

Experimental confirmation of Bell's theorem is reported, using the recently developed method to observe three-photon entanglement, or ‘Greenberger–Horne–Zeilinger’ (GHZ) states, and finds the results of the fourth experiment to be in agreement with the quantum prediction and in striking conflict with local realism.
Experimental Entanglement Swapping: Entangling Photons That Never Interacted

We experimentally entangle freely propagating particles that never physically interacted with one another or which have never been dynamically coupled by any other means. This demonstrates that…
Entanglement-based secure quantum cryptography over 1,120 kilometres

- 15 June 2020
Entanglement-based QKD is demonstrated between two ground stations separated by 1,120 kilometres at a finite secret-key rate of 0.12 bits per second, without the need for trusted relays, which increases the secure distance on the ground tenfold but also increases the practical security of QKKD to an unprecedented level.
