The seemingly fantasy diamond quantum technology is being practical step by step!
Many applications, including mobile phones and car sensors, use magnetic measurement technology widely.The sensor is usually very large, very expensive, and requires low temperature cooling, which has adverse effects on its availability.In order to obtain the highest sensitivity, diamond drivers have become a compact and portable choice.
recently,Element SixCollaboratorSBQuantum The University of Warwick University has released cooperation progress based on the application expansion of quantum diamonds.
Diamond instead GPS To navigate
If you can use diamonds instead GPS Come navigation, what will happen?
A family name SBQuantum（SBQ) Start -up company ZhengheElement SixCo -developed and developed a navigation technology based on diamond -based quantum magnetic meter, trying to completely change the navigation system in a place without a global positioning system.
It is understood,Element Six and SBQ Keep cooperating, the earliest is in 2018 The British annual quantum display activity met.Element Six for SBQ Provides the first batch of diamond samples required to manufacture diamond -based quantum magnetic instrument prototypes.At present, the company has created and sold diamond -based quantum magnetic meters for industrial and academic purposes, especially for autonomous vehicles.
current GPS The system runs by connecting the satellite.generallyGPS The system will be equipped with a very precise magnetic instrument. It relies on the direction, strength, or relative change of the earth magnetic field in a specific location to provide the most accurate position, height and directional information.However, giant metal structures such as skyscrapers may increase interference.At the same time, because the North Pole and other polar areas have unique magnetic field lines, these systems cannot be launched independently, which often causes the loss or damage of priceless equipment.In addition, in many cases, such as underground or underwater,GPS Nothing.
In order to more accurate positioning, diamond magnetic meter is used for navigation system development, which will improve the accuracy of direction and direction information and achieve navigation under extreme conditions.
As we all know, in the application of quantum mechanics, diamond is a key super material.Nitrogen space(NV) It is a special defect in diamond. It has controllable quantum characteristics, making it feel like an orphan atom at room temperature.These atomic diamond defects can be controlled at room temperature without expensive and bulky low -temperature cooling equipment.
becauseNVThe defective quantum characteristics are very sensitive to the magnetic field, so in diamondNVIt is the ideal material of the high sensitivity magnetic forceometer. Vajrayana can be used to evaluate the direction of the magnetic field and provide higher sensitivity.
Due to the combination of these characteristics, King Kong Stone becomes support GPS The excellent choice of navigation extremely accurate sensors.
Vajrayana quantum magnetic meters, it uses quantum characteristics to measure the small direction and strength of the small and almost unaware of the abnormal direction and strength in the earth's magnetic field.Combining it with the magnetic field map, you can accurately locate your location on the earth. Theoretically, it can be accurate 50 About meters.
Compared with the current commercial equipment on the market, diamond quantum magnetic meters have a number of advantages, including room temperature operations, large bandwidth, high sensitivity and vector capabilities.These advantages are applicable to many applications, including drones, underground mining cars and autonomous underwater aircraft.
at present,SBQ The entire service solution created by the company is combined with the sensor with a client -specific instrument board, which can be used for navigation and abnormal detection.
CVDVajrayana Promoting Medical Diagnosis
The excellent characteristics of diamonds make it possible to create an advanced quantum medical solution; it is possible to diagnose early heart disease; it is also suitable for magnetic heart movement (MCG) Waiting for medical diagnosis procedures ...
It is understood that Element 6 has cooperated with Warwick University for ten years, and gradually improved the accuracy and sensitivity of diamond quantum technology in this process.
Among them, a research project, after five years, the sensitivity of the magnetic instrument has increased 1000 10,000 times, from the threshold of the Mrsla to the Natsla threshold (as shown in the figure below), which makes this technology apply to the preliminary diagnosis of heart disease and the identification of reinforced corrosion.
At present, the tool developed by the team can detect steel corrosion, and I believe that heartbeat pulse may be measured soon.The next task is to convert this innovative method into a sale reality.
Associate Professor of Warwick University Gavin Morley Dr. said that in the future, he hopes to reduce the product size and make it easier to carry. It can be installed in a backpack.
In response to the next plan, the research team of Winwei's University is still considering the brain magnetic map (MEG),this is oneThe technology of detecting the brain signal may become a potential application in the future.Although diamond magnetic maps are more difficult to achieve, because the magnetic field of the brain is smaller than the magnetic field of the heart, it may be used to diagnose schizophrenia and early Alzheimer's disease.
