Hybrid Qubits Computing

Authors: George Rajna

By constructing a hybrid device made from two different types of qubit-the fundamental computing element of quantum computers-they have created a device that can be quickly initialized and read out, and that simultaneously maintains high control fidelity. [51] Researchers have demonstrated that an amoeba-a single-celled organism consisting mostly of gelatinous protoplasm-has unique computing abilities that may one day offer a competitive alternative to the methods used by conventional computers. [50] For the first time, researchers have used tiny gears made of germanium to generate a vortex of twisted light that turns around its axis of travel much like a corkscrew. [49] Physical systems with discrete energy levels are ubiquitous in nature and form fundamental building blocks of quantum technology. [48] In a similar vein, scientists are working to create twisting helical electromagnetic waves whose curvature allows more accurate imaging of the magnetic properties of different materials at the atomic level and could possibly lead to the development of future devices. [47] In a recent study, materials scientists Guojin Liang and his coworkers at the Department of Materials Science and Engineering, City University of Hong Kong, have developed a self-healing, electroluminescent (EL) device that can repair or heal itself after damage. [46] A team of researchers based at The University of Manchester have found a low cost method for producing graphene printed electronics, which significantly speeds up and reduces the cost of conductive graphene inks. [45] Graphene-based computer components that can deal in terahertz "could be used, not in a normal Macintosh or PC, but perhaps in very advanced computers with high processing rates," Ozaki says. This 2-D material could also be used to make extremely high-speed nanodevices, he adds. [44] Printed electronics use standard printing techniques to manufacture electronic devices on different substrates like glass, plastic films, and paper. [43] A tiny laser comprising an array of nanoscale semiconductor cylinders (see image) has been made by an all-A*STAR team. [42]
