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.

Recently, new progress has been made in high-dimensional quantum computation by the superconducting quantum computation team​ of Beijing Academy of Quantum Information Sciences and Professor You Li’s team from the Department of Physics at Tsinghua University. The feasibility of a multi-level system based on a superconducting transmon as a quantum computing unit has been experimentally verified.

Quantum Cloud Group of BAQIS and the Institute of Physics, Chinese Academy of Sciences, used a superconducting quantum chip with 10 bits and 9 couplers arranged in one dimension to realize the promotion of the Aubry-André-Harper (GAAH) model for the first time. The different kinetic properties of the three phases and the phase transitions between them were observed at the multi-particle dynamics level.
