Dutch created quantum radio

Dutch researchers have created an integral chip, which allows you to listen to the weakest radio signal allowed by quantum mechanics. The invention can be applied in medicine, astronomy and physical studies.

Typically, the problem of a weak signal is solved by finding a point where it will be stronger. However, with magnetic resonance tomography in the hospital or in the study of space using a telescope, this option is not suitable. Therefore, a team of scientists from the Delft Technical University decided to go to another way and increase the sensitivity of the device.

They developed a chip that can detect photons or energy quanta, which are the weakest signals that are allowed by the theory of quantum mechanics.

According to scientists, in the quantum world, the energy consists of discrete elements that determine the minimum steps of changes, but they are too small so that they can be noted. Until recently, a similar situation was also to radio waves. However, the diagram presented allows you to detect these minimum energy portions in radio signals.

Researchers plan to use the invention to study gravity on the quantum level. In their opinion, such experiments will allow you to check whether it is possible to achieve a quantum superposition of the very space-time.
