Recently, scientists from Beijing Academy of Quantum Information Science , Tsinghua University, and Hong Kong University of Science and Technology published in Physical Review Letters on July 5th, 2023 to report that when the thickness of a two-dimensional semiconducting PbTe film is reduced from 18 to 2 atomic layers, the size of its electronic band gap exhibits an even-odd layer oscillation.

Recently, the Quantum Operating System Group at Beijing Academy of Quantum Information Sciences (BAQIS) made significant progress in the design of noise-resistant quantum circuits for quantum phase estimation problems.

Quantum Photonics Group of BAQIS, in collaboration with a team from Nanjing University, has recently published a research article entitled “Experimental quantum communication overcomes the rate-loss limit without global phase tracking” in the prestigious journal of Physical Review Letters, reporting a drastically simplified setup for long-distance quantum communication.

Recently, the Quantum Cloud group of BAQIS and the Institute of Physics, Chinese Academy of Sciences, realized an analogue lattice black hole model for the first time on a superconducting quantum chip with tunable couplers, and observed analogue Hawking radiation and the related entanglement dynamics.
