The principle of uncertainty in Heisenberg is not broken. These physicists found a gap

Old physical wisdom can become simple. Take, for example, that the idea is generally better for the complex science Observatory. But there is another person in which researchers wander around in an indirect manner, despite his impressive success rate: when the base cannot be broken, you do not fight it. Just go.

in Science progress A paper published today, the physicists did so. Researchers found a way to avoid the principle of uncertainty in Heisenberg – a huge base dictating the corridor of quantum molecules – to reach the “Goldilocks Zone” for uncertainty that allow scientists to extract only the most relevant information from the quantum system. This practical approach can greatly benefit future developments in quantum sensing for navigation, medicine or astronomy, according to researchers.

“We are really taking advantage of this concept of moving the uncertainty about it,” Christophe ValhaoTell the main author of the study and physicist at the University of Sydney in Australia, Gizmodo during a video call.

Vallao explained that the particle was on the ruler, so the new approach will not measure its location or its exact momentum. Instead, the idea is to measure something called the normative status of the particle and its momentum, which is “different variables that give the same type of information.”

Walk around heisenberg

The principle of the uncertainty Heisenberg, presented by the physicist called 1927, dictates that it is impossible to close each of the standards – location and momentum – at the same time. Simply put, there is a comparison between the two that appears as a basic behavior of measurements in quantum mechanics.

Valhao said that the new approach “is redistributing uncertainty in a way that helps us.” It sacrifices “large-scale and universal” information-the actual status of the particle and its momentum-for a more clear way of small changes in the status and momentum of the particle. The last information will be more related to quantum sensing, which depends on quantum mechanical rules to detect and track small signals.

Quantum marriage

To verify the correctness of this idea, the team employed quantum computing experts to develop a protocol based on its approach 2017 paper A similar strategy determines. In the end, the researchers arrived at the “designed quantum system” inspired by both quantum sensing and quantum computing, according to Valvo.

And Valo said: “Quantitative computing and quantitative sensing are two sides of the same currency.” “One of them tries to get rid of noise; the other tries to measure noise or signal. In theory, the more you can measure the signal, it is better to correct the noise as well. So it often works side by side.”

Specifically, they wanted to know whether the new sensor technology could help researchers distinguish between small signals between the noise that stimulates errors in the quantum computer. For their pleasure, they measured the standard position and momentum trapped inside the quantum computer.

“It is a different way of a basic difference in the considering quantum sensing-using the symbols of correcting quantum errors, now traditionally, for quantum sensing.” “We believe that this technique of empowerment (may) spoil more subway technologies (and transform) how we do the current sensing. Through” metolog techniques “, Valhaw refers to the scientific study of the various tools and tools used to take accurate measurements.

Literature about quantum technology grows at amazing speeds. Valhao said it is a great time to explore how different fields can meet to create innovative solutions. Many opportunities appear, and it is difficult to focus on one – but there is no doubt that we live in an exciting time for all quantitative things.
