Researchers from Sandun University and Chancung National University have taken an important step towards more reliable quantum technologies. Scientists first, using a special method for a single Cropy local filtration (SCLF), showed that hidden quantum correlation was removed from three -dimensional confusing situations. Published in İş Magazine Physical Review Letters (PRL).
Quantum confusion – the basis of the operation of quantum computers and communication systems – is extremely sensitive to external noise. This noise destroys the connection between the particles and reduces the effectiveness of technology. However, the SCLF allows you to “clean” a confusing situation without requiring multiple copies and complex interaction between the photons thought to be necessary before.
“It is almost impossible to prepare perfect confusion, Professor He Lou, the joint author of the study. “Therefore, we were looking for a simple way to restore in practice. And they found it in the SCLF method.”
The researchers worked with quantum situations known as Werner states, which was often accepted as “very noisy özellikle to show weakness – a fundamental quantum effect. However, by applying SCLF to the Trechnurovnoye (three -dimensional) photon system (light particles), scientists managed to remove and correct the phenomenon of not being linearly -for the first time the theoretician Popescu proposed such an opportunity 30 years ago.
He added that even a “dirty” quantum state of Toy Liang from the QVT EFİT Center contains strong sources ”.
The work of the team leads to simpler and more scalable methods of cleaning and strengthening quantum connections, especially in multi -dimensional photon systems. In the future, researchers plan to adapt the method for higher measurements using integral optics that will overcome the restrictions of volumetric optical installations.
