Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electromagnetic measurement systems are limited by the power of electromagnetic waves, which restricts their sensitivity, especially in detecting small perturbations such as biological molecules or gravitational waves.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electromagnetic wave power is increased to improve measurement sensitivity, then detection capability is improved, but system complexity and energy consumption increase
Solution Approach 1:
The patent changes the coupling configuration parameter from reciprocal to non-reciprocal, creating an asymmetric coupling relationship where the second resonator influences the first but not vice versa. This parameter change enables enhanced sensitivity to perturbations without requiring increased electromagnetic wave power, as the non-reciprocal coupling creates a more responsive system to external disturbances.
2Productivity
If non-reciprocal coupling is implemented to enhance measurement rate, then detection speed is improved, but device complexity increases
Solution Approach 1:
The patent introduces a measurement line as an intermediary element that couples to the first resonator and provides the readout signal. This intermediary facilitates the detection of perturbations by translating the complex non-reciprocal coupling effects into measurable signals, thereby enhancing the measurement rate while managing the complexity through a dedicated measurement interface.

AI summary
Technologies for quantum sensing are disclosed. In the illustrative embodiment, a sensor system may be operated by coupling an electromagnetic wave from a measurement line to a first resonator. The sensor system includes a second resonator that is non-reciprocally coupled to the first resonator. In the absence or a perturbation, there is no reciprocal coupling between the first resonator and the second resonator, but a perturbation may cause reciprocal coupling between the first and second resonator. With appropriate selection of the non-reciprocal coupling, the signal at the output of the measurement line may allow for fast determination of whether the perturbation is present.
