Ion trap and quantum computing device

The utility model discloses an ion trap and a quantum computing device. The ion trap comprises a vacuum cavity, an ion trapping device and a particle beam generating device, wherein the particle beam generating device is arranged at the position of a preset flange interface and is used for jetting a particle beam along the direction of a non-optical flange interface; wherein the particle beam comprises an atomic beam or an ion beam; the non-optical flange interface direction comprises a normal direction of a preset flange interface on the ion trap vacuum cavity; the preset flange interface comprises a vacuum flange interface and an electrical flange interface. According to the embodiment of the utility model, the particle beam generating device is arranged at the position of the preset flange interface, so that the particle beam is jetted along the direction of the non-optical flange interface, and the suppression of Doppler frequency shift and Doppler broadening is realized. 本文公开一种离子阱及量子计算装置，包括：真空腔体、离子囚禁装置和粒
