Quantum clocks will become a more feasible and real-world technology thanks to new
Scientists have developed a solution: a special package, which is a "box" with a volume of about 120 liters and weighing less than 75 kg. The work was published in the journal Quantum Science and Technology.
The new design is based on the cameraUHV of a smaller size than any previously used in the field of quantum timekeeping. This chamber can be used to trap atoms and then cool them down to a value that is very close to absolute zero. So they have reached a state in which they can be used for precision quantum sensors.
Physicists managed to capture almost 160,000ultracold atoms inside the chamber in less than a second. In addition, they have shown that they can transport the system over 200 km before setting it up to be ready for measurements in less than 90 minutes. The system was able to withstand an increase in temperature of 8 degrees above room temperature during transportation.
The lead author of the new work, Dr. Yogeshwar Kale,noted in a press release accompanying the new study that "the stability and accuracy of optical clocks make them critical to many future information networking and communications."
Once people have a system readyFor use outside the laboratory, scientists will be able to use them, for example, in terrestrial navigation networks, where all such clocks are connected via optical fiber and begin to “communicate” with each other. Such networks will reduce humanity's dependence on GPS systems, which can sometimes fail.
“This portable optical watch will not only helpimprove geodetic measurements—fundamental properties of the Earth's shape and changes in gravity—but will also serve as precursors for monitoring and identifying geodynamic signals such as earthquakes and volcanic eruptions in the early stages,” the scientists conclude.
