Scientists have opened a new way to measure time: what is known about this technology

< IMG SRC = "/Uploads/Blogs/2A/F5/IB-FRU07R6SU_FC931624.jpg" Alt = "Scientists have opened a new way to measure time: what is known about this technology"/> ~ ~ < p > Researchers at the University of Upsali in Sweden have offered a new way of measuring time that does not require traditional CEA & Rsquo; Their method is based on the use of Ridberg atoms & mdash; These are atoms whose electrons are at very high energy levels that makes them extremely sensitive to external fields and interactions.

< P > About it writes a resource Sciencealert.

< P > People used to count the time to use watches with pendulums and arrows. At the same time, seconds between & ldquo; then & Rdquo; and & ldquo; now & Rdquo;.

< P > A new way of measuring time does not have VE & Rsquo; Languages ​​before the start and completion of the event.

< p >Yes, Marta Bergoltz, the head of the research group, explains: & ldquo; if you use a counter, you need to determine zero. You start counting from some moment, but at the quantum level this approach does not work & Rdquo;.

< P > The new method of determining time is based on the use of Ridberg atoms & ndash; These are atoms whose electrons are at very high energy levels, which makes them extremely sensitive to external fields and interactions. These electrons rotate far from the nucleus of the atom. Scientists use lasers to create such states.

< p >The direction of laser radiation on atoms causes their electrons to switch to higher energy levels. This phenomenon is often used in various fields of physics. Researchers can use a second laser to monitor changes in electrons. The following methods & ldquo; pumping-probing & RDQUO; allow you to measure super -fast processes.

< p > Mathematical description of Ridberg electrons is called Ridberg wave bag. When several such wave packages interact, they create interference pictures. These patterns are unique for different time intervals. They reflect the evolution of wave packages relative to each other.

< p > Swedish scientists focused precisely on these & ldquo; prints & rdquo; time. They conducted a series of experiments with excited helium atoms. The results of the studies were compared with theoretical forecasts. Experiments have confirmed the reliability of this time measurement method. < Br />The new approach has significant advantages over traditional methods. & ldquo; preference is that you do not need to start a clock & Rdquo;, & ndash; Notes Bergoltz. Researchers simply analyze the structure of interference. This allows you to accurately determine the time interval.

< P > Time tags are based on the structure of quantum interference. It is similar to determining the speed of a runner without a stopwatch. Instead we compare it to other athletes whose speed is known.

< P > The accuracy of the method is striking with its extraordinary precisiveness. With the help of the Ridbberg state interference, events can be measured up to 1.7 trillion second. This level of accuracy opens new horizons for quantum research.

< P > Future experiments can expand the capabilities of this method. Researchers plan to use different atoms instead of helium. They also consider the use of laser pulses of different energy. This will create a wider & ldquo; directory & rdquo; time tags.

< P > Technology can significantly affect the development of quantum physics. It will help you study the fast processes that have previously been impossible to measure. Research results are published in a prestigious scientific journal Physical Review Research.

< P > The new time measurement method demonstrates the amazing capabilities of quantum physics. He confirms that even basic concepts, such as time, become new at the quantum level. Further research in this direction can change our fundamental understanding of the nature of time.
