Quantum physicists at the University of Warsaw have discovered new applications for quantum catalysis—the quantum equivalent of chemical catalysis used in industry—revealing that quantum catalysts are useful in many more setups than previously known. The breakthrough could prove pivotal in future quantum key distribution networks or distributed quantum computing.
A team of quantum physicists from the Centre for Quantum Optical Technologies, University of Warsaw, Poland, has found a complete solution to the vexing problem of whether catalytic transformations from one initial quantum state to another desired quantum state are possible. The results of their study—released on 5 October 2021 in Physical Review Letters—prove the utility of catalysts in boosting quantum processes and quantify the amount of entanglement available for quantum information processing. The breakthrough is particularly pertinent to any quantum technology involving two or more distant labs; for instance, quantum key distribution networks or distributed quantum computing.
