1Loss of time
If the intensity of the microwave is enhanced to perform electron spin quantum operation in a short period of time, then the measurement time is reduced, but it is difficult to enhance the microwave intensity with conventional magnetic measurement devices
Solution Approach 1:
The patent combines a coil and a capacitor to form a resonant circuit that generates microwaves. The coil produces a magnetic field while the capacitor stores electrical energy, and their combination creates a resonant system that amplifies the microwave output intensity, enabling enhanced power for rapid electron spin quantum operations.
Solution Approach 2:
The patent employs a resonant circuit that can be tuned to specific frequencies to dynamically adjust and maximize microwave output intensity. By adjusting the resonant frequency of the coil-capacitor system, the device optimizes power delivery to achieve high-intensity microwaves for shortened measurement times.
2Speed
If a high frequency magnetic field is applied to perform electron spin quantum operation based on Rabi oscillation, then the measurement speed is improved, but the device complexity increases due to the need for enhanced microwave generation capability
Solution Approach 1:
The coil in the patent serves multiple functions: it generates the magnetic field necessary for electron spin manipulation and simultaneously acts as an inductor in the resonant circuit for microwave generation. This multi-functionality reduces device complexity while maintaining high measurement speed through Rabi oscillation.
Solution Approach 2:
The patent changes the operational parameters of the coil by utilizing it both as a magnetic field source and as a resonant element. By adjusting the frequency and intensity parameters of the coil current, the system achieves both rapid electron spin manipulation and simplified device architecture.
