A new technology capable of processing the vast amount of information generated by quantum systems, developed by researchers at the Niels Bohr Institute in collaboration with the University of Münster and Ruhr University Bochum, was recently published in the journal Science Advances.
According to the report, a quantum simulator is a special-purpose computer that simulates quantum systems by processing quantum information that is difficult to process by classical computers. And deterministic single-photon light sources, capable of generating quantum bits at very high rates and speeds, coupled to specially designed integrated photonic circuits, are able to process quantum information with sufficient speed and quality without degrading susceptible quantum states.
This means that our scientific work has taken the first step toward developing photonic quantum devices that can, for example, describe and simulate complex quantum systems like the vibrational dynamics of biomolecules.
"When the number of quantum bits increases, the processing of quantum information requires an exponential increase in the capacity of classical computers. This means that even fairly simple quantum mechanical problems cannot be solved on a classical computer." . The bigger challenge, says Stefano Paesani, one of the researchers, is to handle photons emitted in large numbers at the speed of light, which must happen very fast and without loss, not to mention not allowing too many errors to occur.
In this regard, the research team collaborated with the University of Münster to develop photonic circuits capable of handling quantum bits from photon sources efficiently and fast enough; and to bring the two systems together. The team then also developed a "roadmap" for scaling up the technology. "We are now opening the door to applicants," said Stefano Paesani. Stefano Paesani said.
