The physicists at the Institute of Science and Technology Austria (IST Austria) have just invented a new kind of radar that uses quantum cuttlefish as a method of detecting objects.

Enhanced Sensitivity of Photodetection via Quantum Illumination.

Such effective integration of quantum mechanics and equipment can have a real impact on the biomedical and safety industries, and the discovery is widely commented around the world. We would like to remind you that the quantum state of tangled is a phenomenon that has an impossible classic physics feature, that the state of the entire system is better defined than the state of its parts that remain connected, regardless of their distance. Moreover, quantum tangles can also be possible between systems that do not exist... at the same time.

This is where the project was based by Professor Johannes Fink's group of scientists from the Institute of Science and Technology Austria (IST Austria), Stefano Pirandola of the Massachusetts Institute of Technology (MIT) and David Vitali of the Italian University of Camerino, to learn new detection technology called microwave quantum illumination. A prototype, also called quantum radar, is able to detect objects in thermal noise conditions where conventional radar systems fail. Technology is therefore potentially used in biomedical imaging or safety scanners that require minimal power in addition.

The rules behind this device are simple, instead of using conventional microwaves, scientists have tangled up two groups of photons, called signal and idle respectively. The signals are sent to the object of interest, while idle are measured during relative isolation, free of obstructions and noise. When a feedback signal arrives from the signals, the call between the signals and the idle is dropped, but there is a small number of correlations, creating a formula that describes the presence or absence of the object being sought.

We have demonstrated the performance of our quantum radar. Using quantum tangs generated at several thousand degrees above absolute zero, we were able to detect objects with room temperature,' said Shabir Barzanjah, whose earlier research allowed scientists to theoretical substructure the project. And while such quantum tangles are inherently fragile, the radar equipment O cannot be based on conventional radars in several respects.

Quantum Entanglement.

It is enough to mention that, with low energy levels, traditional radars suffer from poor sensitivity, which is not a problem for quantum radar: - the main message from our research is that quantum radar is not only possible in theory but also in practice. When we combine it with classic solutions in the same conditions, we can see that with very low numbers of low signal photons, the supported quantum detection can be excellent, adding scientists. Many similar evidence, as we demonstrated, was important milestones for technological improvements. This will be very interesting, observe the future implications of this study,' the authors add.
