One-step implementation of nonadiabatic geometric fSim gate in superconducting circuits
M. -R. Yun, Zheng Shan, Li-Li Sun +3
Due to its significant application in reducing algorithm depth, fSim gates have attracted a lot of attention. However, during the implementation of quantum gates, fluctuations in c…
