Quantum Photonics Group of BAQIS has recently published a research article entitled "Twin-field quantum key distribution without optical frequency dissemination", reporting their invention that has substantially simplified long-distance secure quantum communications.

Quantum Photonics Group​ of BAQIS has recently published a research article entitled "Ultra-narrowband interference circuits enable low-noise and high-rate photon counting for InGaAs/InP avalanche photodiodes", reporting the invention of a novel readout circuit that can effectively suppress electronic background noise and thus enable low-noise and high-rate single photon counting.

Recently, the Topological Quantum Computation Group of BAQIS, in collaboration with the researchers of Tsinghua University and Institute of Semiconductor, Chinese Academy of Sciences, has significantly improved the InAs-Al nanowire device quality, and observes ZBPs quantized at 2e2/h with 5% tolerance (see the figure below).

A recent work on one-way EPR steering in higher-dimensional system has been accomplished by Dr. Qiang Zeng, who works as assistant researcher in Beijing Academy of Quantum Information Sciences.
