Hybrid entanglement is an essential quantum resource of hybrid quantum information processing, which combines the advantages of discrete-variable (DV) and continuous-variable (CV) quantum information processing and overcomes their disadvantages. In quantum information processing, a feasible approach for enhancing the ability of quantum information processing is increasing the degree of freedom carried by the entangled state. Recently, hybrid CV-DV entanglement carrying orbital angular momentum (OAM), which involves three degrees of freedom, including polarization, cat states, and OAM, is presented. This work extends the degree of freedom for hybrid entanglement, which provides a new quantum resource for hybrid quantum information processing.

Researchers at the University of Bristol have made a breakthrough in the development of “life-like” synthetic materials which are able to move by themselves like worms. Scientists have been investigating a new class of materials called ‘active matter’, which could be used for various applications from drug delivery to self-healing materials.

Researchers at the Karlsruhe Institute of Technology (KIT) have synthesized a Bi₅^--ring, a molecule with five bismuth atoms, and stabilized it in a metal complex. Their discovery fills a gap in chemical knowledge and enables future applications in materials research, catalysis, and electronics. Their findings have been published in Nature Chemistry.

Is it possible to tile a surface with a single shape in such a way that the pattern never repeats itself? In 2022, a mathematical solution to this “einstein problem” was discovered for the first time. Empa researchers have now also found a chemical solution: a molecule that arranges itself into complex, non-repeating patterns on a surface. The resulting aperiodic layer could even exhibit novel physical properties.
