Quantum technology is a frontiert, echnology field that has developed rapidly in recent years, and the development of this technology has caused much attention all over the world. In addition to the well-known directions of quantum computing and quantum communication, research on quantum sensors is also gradually being carried out.

Sensors have advanced into the quantum realm

Quantum sensors are designed according to the laws of quantum mechanics and quantum using effects. In quantum sensing, the electromagnetic field, temperature, pressure and other external environments directly interact with electrons, photons and other systems and change their quantum states. By measuring these changed quantum states, high sensitivity to the external environment can be achieved. Measurement. Compared with traditional sensors, quantum sensors have the advantages of non-destructiveness, real-time, high sensitivity, stability and versatility.

The United States released a national strategy for quantum sensors, and the National Science and Technology Council (NSTC) Subcommittee on Quantum Information Science (SCQIS) recently released a report titled “Putting Quantum Sensors into Practice”. It proposes that institutions which lead R&D in Quantum Information Science and Technology (QIST) should accelerate the development of new quantum sensing methods, and develop appropriate partnerships with end users to increase the technological maturity of new quantum sensors.Promising technologies should be identified by conducting feasibility studies and testing quantum prototype systems with QIST R&D leaders when using the sensor. We want to focus on developing quantum sensors that solve their agency’s mission. It is hoped that in the near to medium term, within next 8 years, action on these recommendations will accelerate the key developments needed to realize quantum sensors.

China’s quantum sensor research is also very active. In 2018, the University of Science and Technology of China developed a new type of quantum sensor, which has been published in the famous journal “Nature Communications”. In 2022, the State Council issued the Metrology Development Plan (2021-2035) which is proposed to “focus on research on quantum precision measurement and sensor device preparation integration technology, and quantum sensing measurement technology”.
