Three Polish scientists from the Faculty of Physics at the University of Warsaw and the Center for Optical Quantum Technologies have created the world’s first quantum processor.

The authors of the innovative project – Mateusz Mazelanik, Adam Leszczynski and Michal Parniak – proved that information can be transmitted through the light spectra emitted by all objects. For example, by the spectrum of the light of a star, the device can determine what elements it consists of.

“We extract as much information as possible from individual photons, so the measurements become very efficient,” said Mateusz Mazelanik.

According to Mikhail Parnyak, the device and algorithm of the invention not only make it possible to better extract the information carried by light, but can also “allow better” bringing information into the light.

This could also be used, for example, in telecommunications solutions, where it is becoming increasingly important to record information using light and read it as efficiently as possible, they say.

“Our spectrometer exceeds the classical limit by using 20 times fewer photons than a hypothetical conventional spectrometer,” explained Mazelanick.

The Center for Optical Quantum Technologies is an international research program funded by the Polish Science Foundation with co-funding from the European Regional Development Fund.

The project was funded by the Ministry of Science through a Diamond Grant led by Mazelanik and by the National Science Center through a PRELUDIUM grant led by Adam Leszczynski.
