(1) Non-destructive:
In quantum manipulation, the measurement may arouse the wave function reduction of the measured system, and the sensor may also arouse the state transformation of the system. Therefore, the photolysis between the quantum sensor and the system should be fully considered in the measurement. Due to the fact that state detection in quantum manipulation is fundamentally different from state detection in classical control, the state wave function reduction process that the measurement may evoke has already destroyed the state itself. Therefore, non-destructiveness is one of the top assumptions that quantum sensors should be crucial to. When carrying out the in-bone detection, it can be assumed that the quantum sensor is considered as a local part of the system, or as a disturbance of the system, the sensor and the measured object interact with the Hamiltonian in the evolution of the state of the total attendance system;
(2) Real-time:
Based on the characterization of measurement in quantum determination, specificity is the rapidity of state evolution, driving real-time to become an important indicator of quality evaluation of quantum sensors. The real-time measurement capability of the quantum sensor should be consistent with the current state of the target, and the quantum state evolution of the target can be stared at if necessary. When planning the quantum sensor, it is necessary to consider how to solve the measurement lag problem.
(3) Sensitivity:
Since the most important function of the quantum sensor is to achieve the desired succession of the micro target to be measured, it is required that the target's small thinking and change can be captured, therefore, when planning the quantum sensor, it is necessary to consider that its sensitivity can also meet the actual requirements;
(4) Settle down:
In quantum domination, the state of the controlled target is easily affected by the environment, and the quantum sensor may also provoke the instability of the target or the sensor's own state when detecting the quantum state of the object. The art of solving the problem is to introduce environmental engineering considerations, and consider using art such as refrigeration traps and high temperature retentors to provide security.
(5) Versatility:
The quantum system is not afraid of a complex system, the interaction between subsystems or between sensors and systems is easy, and the practical application is expected to reduce the human influence and the downward problem driven by multi-step measurement. In this regard, why not integrate more functions, such as sampling, selling, measurement, etc. into a uniform quantum sensor, and integrate appropriate intelligent control indexing methods into it? Urban, multi-functional quantum sensors are planned.
Quantum sensors have properties that are not lacking in a few classical sensors. When planning a quantum sensor, it is important to propose that the quantum world should not directly measure quantitative changes to replace measurable quantities, but also to evaluate the properties of quantum sensors in terms of non-destructiveness, real-time, sensitivity, stability, and versatility.
The characteristics of quantum infrared sensor: the use of advanced mature integrated circuit high energy saving, annual power consumption is only 2 ~ 3 degrees. The use of human infrared sensing principle, supplemented by high-precision sensors, without sound and switch control, people come to light, people go light off, the day is not bright, the night is bright (due to the strong light during the day, the sensor automatically closed), thus effectively ensuring the quiet living space in the building.
