Reference News Network reported on November 11 According to the British "Financial Times" website reported on November 9, under the support of millions of British pounds provided by the British Ministry of Defense, British scientists made The world's first quantum "compass" - an anti-jamming navigation device that does not rely on global positioning satellites (GPS).
The report says that the device can determine the exact location of anything on the planet without being disturbed because it does not rely on external satellites.

The report said that Joseph Cotter, a researcher at the Imperial Institute of Cold Matter at the Imperial Institute of Technology, said: "It is completely immune to outside influences. If you want to be a large vessel or autopilot for a long time." Car navigation, its use is particularly large, no need to send or receive any other signals."
The report said that the Ministry of Defense has been investing in the construction of an independent navigation device. It believes that such a device can be used for special purposes on its nuclear submarines, which require secret navigation and isolation from the outside world.


UK team has demonstrated a transportable, standalone quantum accelerometer at the National Quantum Technologies Showcase.
The quantum accelerometer has precision and accuracy possible by measuring properties of supercool atoms. At extremely low temperatures, the atoms behave in a ‘quantum’ way, acting like both matter and waves.

The report believes that although GPS is the de facto global navigation system, its dependence on space satellites means that it may be blocked, intercepted or obstructed.
The report said that, in particular, it is extremely vulnerable to vandalism or attack. "The satellite may sometimes lose its signal due to space environment or high-rise buildings, or it may be maliciously shot down or deceived, so you will think that you are in a certain place, but it is not." he said. "On the earth, GPS signals can't be received anywhere."

The report says that this new system called quantum accelerometer works by measuring the speed of objects over time. The change that has taken place. Although accurate accelerometers exist in devices such as cell phones and laptops, they must be recalibrated frequently. If used for navigation, they can only work for up to several hours at a time.

This quantum device measures the very low temperature - near absolute zero - the movement of ultra-cold atoms; in this ultra-cold state, it is manipulated and controlled with a custom-made powerful laser. they. The laser was developed by Glasgow-based MSquared for nearly three years.

The report quoted Grammar Malcolm, founder and CEO of MSquared, as saying: "Now the pirates are very sophisticated and will interfere with the ship by disturbing the GPS, enticing the ship to hit the rocks or boarding the ship to gain control. In the area of ​​defense and security, this may be a bigger problem because the resilience and security of cities and countries will be affected. This new device is an absolute reference to the atomic level.”

The report said that the development of the navigation device was funded by the Defense Department's research department, the Defense Technology Laboratory, the UK Engineering and Physics Research Council, and the UK Innovation Agency.

Introduction, in 2013, quantum research was identified as a priority area by the British government, with a focus on military technology. Since then, through the British National Quantum Technology Program, the UK government has invested 270 million pounds (about 350 million US dollars) in projects in this field within five years.
