A weak radio signal is not a problem just when you're trying to tighten into your favorite radio station, a weak signal is a huge problem for MRIs in hospitals and telescopes that look to & # 39 ; r space.
As a rule, we set a weak signal by moving closer to the source or to choose a different radio station but what, if instead, could we listen to us more carefully? Scientists at Delft Technology University have created a quantum circuit that enables them to listen to the weakest radio signal allowed by quantum mechanics. Their research was published Friday in the magazine Science.
Not your Grandpa Radio
A wirk of quantum mechanics is the theory that energy can only find specific units, from the "quanta" name. Only whole units are available, nothing between them. "Say that I'm pushing a kid on a swing," said lead researcher Mario Gely, "In the classic theory of physics, if I want the child to go a little faster, I can give them a little push, giving them more from a speed to them and more energy. Quantum mechanics say something different: we can only increase the energy of the child at one time and we can only push half of that amount & # 39 ; n possible. "
Before the Delft team develops their circuit, we can only adapt radio signals in the form of "small push" or an incredible small amount. With a new quantum circuit, researchers can draw to a certain quanta of radio frequencies. The more detailed multitudes could help to improve the accuracy of MRIs and radio telescopes but it can also learn more about quantum mechanics, gravity and physics.
The quantum circuit of Delft's team could help bring new ways of scientific discovery. They next hope to explore the way in which gravity interacts with quantum physics, something that is still physics factors today.
"Using our quantum radio, we want to listen to the quantum controls of heavy objects, and explore experimentally what happens when you mix quantum mechanics and gravity," says Gely. "Such experiments are hard, but if that were successful, we would be able to prove if we can make a huge superposition of time itself."
Quantum's detail is the theory of mathematical physics where some variables of places between them are slightly different than they usually, resulting in a slightly different mathematical understanding of universe. The proposed quantum superposition experiment is one that Gely would say "proves our understanding of quantum mechanics and general relevance."
