Satellite-based entanglement distribution over 1200 kilometers
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.
Satellite-to-ground quantum key distribution
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.
Experimental long-distance decoy-state quantum key distribution based on polarization encoding.
The decoy-state quantum key distribution (QKD) with one-way quantum communication in polarization space over 102 km is demonstrated and can really offer the unconditionally secure final keys.
Decoy-state quantum key distribution with polarized photons over 200 km.
A novel and economic way of synchronization method is designed and incorporated into the system, which allows to work at a low frequency of 40kHz and removes the use of highly precise clock.
Satellite-Relayed Intercontinental Quantum Network.
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 demonstration of a hyper-entangled ten-qubit Schr\
Creating entangled photon states becomes technologically ever more difficult as the number of particles increases, and the current record stands at six entangled photons. However, using both their
Ground-to-satellite quantum teleportation
The demonstration of a ground-to-satellite uplink for reliable and ultra-long-distance quantum teleportation is an essential step towards a global-scale quantum internet.
Experimental Ten-Photon Entanglement.
This work created a state-of-the-art platform for multiphoton experiments, and enabled technologies for challenging optical quantum information tasks, such as the realization of Shor's error correction code and high-efficiency scattershot boson sampling.
Observation of eight-photon entanglement
Researchers demonstrate the creation of an eight-photon Schrodinger-cat state with genuine multipartite entanglement by developing noise-reduction multiphoton interferometer and post-selection
Experimental measurement-device-independent quantum key distribution.
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.
