PRX Quantum: Simultaneous Gate Operations on Superconducting QubitsThe Superconducting Quantum Computing Group of Beijing Academy of Quantum Information Sciences analyzed the crosstalk errors and their impact on the parallel quantum gates in detail, which can provide inspiration and meaningful guidance for the design of scalable superconducting quantum processors.
Advances achieved in nanowire-based Majorana systems by topological quantum computation group of BAQISThe topological quantum computation group has recently achieved several progresses in exploring a new Majorana nanowire material and developing new method of distinguishing Majorana zero modes (MZMs) from Andreev bound states. These achievements have been published in four papers on international physical journals including Physical Review Letters, Physical Review B and Physical Review Materials.
Quantum Secure Direct Communication in 100-km FiberRecently, a team of scientists from Gui-Lu Long’s group and Jianhua Lu’s group at Beijing Academy of Quantum Information Sciences and Tsinghua University proposed and realized a new QSDC system. The new system uses phase states for communication and photonic time-bin states for monitoring, respectively, achieving a distance of 100 km in fiber and setting up a new world record.
Physicists from the High-temperature Superconductivity Group Discovered A Novel Type of Resistance Oscillations in CupratesRecently, a team led by Prof. Ding Zhang and Prof. Qi-Kun Xue managed to carry out a systematic transport study in the lightly doped regime. This breakthrough was reached thanks to the recent technical advances in sample fabrications and modulations of the group. Their study, entitled "Little-Parks like oscillations in lightly doped cuprate superconductors", was published in Nature Communications on 14th March 2022.
