British researchers have created the first quantum accelerometer for navigation, which works autonomously and does not depend on external signals or satellites.
Accelerometers measure the projection of the apparent acceleration. With their help, knowing the initial point coordinates, you can determine the current location of the object. They are present in many devices, such as mobile phones and laptops. However, for the correct operation of traditional sensors, regular communication with an external source is required, it is often a GPS satellite navigation system.
The development of a quantum accelerator was engaged in a team of scientists from the Imperial College of London and M Squared and presented. The operation of their devices is based on accurate measurements of the properties of atoms cooled to an extremely low temperature. In such conditions, elementary particles begin to behave not only as matter, but also as waves. When moving in space, they react to acceleration, and the interferometer with a laser fixes the smallest changes.
To determine the current location, the quantum accelerator does not require communication with a satellite or other source for reconciliation. At this stage of technology development, the device is intended for navigating large vehicles, such as ships or trains. However, the principle of its work can also be used in other fundamental scientific research, such as the search for dark energy, gravitational waves.
According to the developers, loss of communication with the satellite system for 1 day will lead to losses by more than $ 1 billion. Therefore, it began the process of commercializing the innovative product and create real applications based on it.
