Royal Navy Says Quantum Navigation Test a Success

Developed by physicists at Imperial College London , a quantum navigation device shoots laser light at about a billion atoms of Rubidium-87 . Then a cloud is generated from the atoms, and when it cools to a temperature close to absolute zero , the atom cloud will undulate. By taking advantage of this property and taking into account the effects of gravity, etc., it is possible to calculate the speed and direction of movement of the device, and it is said that it is possible to determine the position information in detail. . In addition, it is possible to constantly check the ship's position information by measuring the direction of movement of the atomic cloud and the device over time with a quantum accelerometer.
A ship equipped with a quantum navigation system will not only be able to navigate more accurately than charts and compasses, but it will also eliminate the need for satellite-based navigation equipment using GPS, which is prevalent in modern ships.
Colonel Tom Ryan of the Royal Navy said, ``Satellites can sometimes be jammed or interfered.It is also possible that satellites may malfunction.'' It is extremely important for the navy to have a novel method of accurately determining the position of the navy for smooth military operations.'
By eliminating the need for satellite-based navigation equipment, it has been suggested that the introduction of quantum navigation equipment may enable accurate location information to be specified even for submarines, where it was impossible to specify location information using GPS underwater. I'm here.
Missiles, spacecraft, submarines, etc. use a system called ' inertial navigation system ' that simplifies the quantum navigation system. This is a device that can calculate its own position and speed only with the sensors installed without receiving information by radio waves from the outside. If a quantum navigation system becomes a reality, we can expect improvements in the accuracy of everything that uses inertial navigation systems.
The British Navy's experimental ship ' XV Patrick Bracket ' was used for the experiment of the quantum navigation system, and the shipping container for the quantum navigation device was installed on the deck. ``It's a very good experience to actually sail and test in the real world where the magnetic field changes rapidly,'' said Joe Cotter of Imperial College London, who supported the development. 'There are many waves and engine vibrations in the real world that need to be accounted for in order to secure and operate a quantum navigation device properly.'
The state of the experiment of the quantum navigation system jointly conducted by Imperial College London and the British Navy is as follows. A large number of complex devices and machines are lined up in the containers installed on the ship.

Mr. Kotter says, ``Although it is possible to measure position information over a long period of time using only quantum navigation equipment, in the future, it will be possible to obtain more detailed position information using quantum navigation equipment alone without correcting position information using other technologies. should be able to measure,' he said about the future prospects.
Matt Swain of the technology site The Quantum Insider said, 'The successful quantum navigation system experiment represents a major leap forward in naval technology, improving navigation capabilities and operational efficiency in a variety of operational scenarios for the navy. will have a big impact on the
The Royal Navy declined to comment on specific details regarding the application of quantum navigation systems.
