Description
technical field [0001] The invention relates to the field of ion trapping, in particular to a low-drift, low-noise DC high-voltage output circuit. It is suitable for fields such as optical frequency standards, quantum optics, and quantum information that require stable high-voltage output. Background technique [0002] In the field of optical frequency standards, the reference physical systems mainly include atomic systems and ion systems. Among them, the optical frequency standards based on the atomic system are mainly realized by referring to multiple trapped atoms in the optical lattice; while the optical frequency standards based on the ion system are mainly realized. Implemented with reference to trapped ions. The ion system needs the ion trap to use the radio frequency field and the DC electric field to capture and stably trap the ions in a certain space. The DC electric field used to adjust the position of the ions needs to use a DC high-voltage power supply. Accord...
