A simple algorithm to accelerate the processing of quantum information
A researcher from the Department of Physical Chemistry of the UPV / EHU (Spain) has studied the connection of several mathematical models, which were thought very different, by means of a simple mathematical algorithm, in order to accelerate the processing of quantum information. The prestigious international journal npj Quantum Information has just published the results of this research.
Quantum mechanics has revolutionized the world of communications and computers with the introduction of much faster and safer algorithms in the transfer of information. "The Rabi quantum model is a fundamental model that appears in many physical systems, including quantum platforms such as trapped ions or superconducting circuits, which in the near future could be used as hardware of a quantum computer", explains Jorge Casanova member of the research group Quantum Technologies for Information Science (QUTIS) of the Department of Physical Chemistry of the UPV / EHU and author of the work. "This is the simplest mathematical model we have to describe the processes of interaction between light and matter. That is, the Rabi quantum model is the mechanism that matter and light (radiation) have chosen to communicate, "says the researcher at the UPV / EHU.
This work has demonstrated for the first time that several very sophisticated mathematical models that are used to describe different physical phenomena, are within the same quantum model of Rabi. "It's as if the Rabi quantum model was the root of a much more advanced set of mathematical models," says Casanova. "This means that if one interprets the results that the Rabi quantum model predicts, it would have direct access to the predictions of other more complex models," says the researcher. Basically, "we have connected the Rabi quantum model with other more sophisticated mathematical models that were thought to be very different, all this through a mathematical algorithm, that is, through a series of rules that are also quite simple," he adds.

Therefore, "a deeper understanding of the operational mechanism of the Rabi quantum model would allow us, on the one hand, to deal more precisely with the technical problems that the development of a quantum computer has", the author of the work emphasizes. On the other hand, "given that we would now have direct access to other models beyond the Rabi quantum model," Casanova says, "we would also have direct access to changing the most basic operational mechanism of the aforementioned quantum platforms, and consequently of a future quantum computer. "
Jorge Casanova points out that "beyond the possible practical applications that can be derived and that without a doubt are very interesting, as a physicist it seems incredible to me that such a simple model continues hiding secrets like the one we have found". "It is an unexpected advance, from which we still have to learn and extract all possible information to open new avenues of development in the field of quantum computing," adds the researcher at the UPV / EHU.
Jorge Casanova worked at the University of Ulm (Germany) and is currently a researcher Juan de la Cierva in the QUTIS Group of the UPV / EHU. The QUTIS Group is a world leader in simulation and quantum computing, and has made proposals for quantum implementations that have been carried out by the best laboratories in the world. He collaborates with researchers from five continents, and works on a variety of quantum platforms, such as trapped ions, superconducting circuits, quantum photonics, and nuclear magnetic resonance.
