The Quantum Cloud group of BAQIS, collaborated with the Institute of Physics, Chinese Academy of Sciences, University of California, Santa Barbara and Zhejiang University, used 15 fully connected superconducting qubits to observe the phenomenon of entanglement phase transition in random mixed states for the first time. On April 8, 2023, the achievement was published in Nature Communications under the title "Observation of entanglement transition of pseudo-random mixed states".

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).
