Abstract

The invention discloses a circularly polarized frequency-adjustable solid color center microwave control system and method without a phase shifter. The system can generate a circularly polarized microwave magnetic field without the phase shifter, the selective transition of a solid color center energy level is realized, the selective transition of the solid color center energy level in a zero magnetic field environment becomes possible, therefore, favorable conditions are provided for the miniaturization of a solid color center quantum precision measurement device. The system is characterizedin that the system comprises a circularly polarized frequency adjustable antenna with a rectangular antenna frame, a solid color center sample placing area is arranged in a center of the rectangular antenna frame, and a feed port is arranged on a diagonal line in the rectangular antenna frame to receive a microwave signal output by the microwave signal source device.

Description

technical field [0001] The invention relates to quantum precision measurement technology, in particular to a circular polarization frequency adjustable solid color center microwave control system and method without a phase shifter. The feeding port is set on the line to receive the microwave signal output by the microwave signal source device, which can enable the system to generate a circularly polarized microwave magnetic field without a phase shifter, and realize the selective transition of the energy level of the solid color center, which makes the solid color center The selective transition of the energy level in the zero magnetic field environment becomes possible, which provides favorable conditions for the miniaturization of solid color center quantum precision measurement devices. Background technique [0002] In recent years, solid color center materials, such as diamond NV color center (nitrogen-vacancy center), have been widely used in quantum computing, quantum ...
