Scientists Emulate Nature in Quantum Leap Towards Computers of the Future
A team of quantum computer physicists at UNSW Sydney (Silicon Quantum Computing Lab) led by Professor Michelle Simmons has achieved a major milestone in the race to build the world’s first quantum computer. They have built a quantum processor in silicon to simulate an organic molecule with astounding precision. They described in their recently published Nature paper, how they were able to mimic the structure and energy states of the organic compound polyacetylene – a repeating chain of carbon and hydrogen atoms distinguished by alternating single and double bonds of carbon. They utilize the atomic-precision placement accuracy of the scanning tunnelling microscope (STM) to engineer quantum dots with large on-site energies (U ≈ 25 meV) and uniform size to realize a homogeneous linear array for reliable simulation accuracy.
Study Uncovers How Structural Changes Affect the Superconducting Properties of a Metal Oxide
Research opens the door for further study of superconductivity and the creation of more efficient semiconductors. A team led by University of Minnesota Twin Cities researchers has discovered how subtle structural changes in strontium titanate, a metal oxide semiconductor, can alter the material’s electrical resistance. The research can help guide future experiments and materials design related to superconductivity and the creation of more efficient semiconductors for various electronic device applications.
Scientists Solve the Mystery About the Active Phase in Catalytic Carbon Dioxide Reduction
An international research team led by researchers of Stockholm University has for the first time been able to study the surface of a copper-zinc catalyst when carbon dioxide is reduced to methanol. The results – obtained at DESY´s brilliant light source PETRA III – are published in the scientific journal Science. A better knowledge of the catalytic process of methanol synthesis and the possibility of finding even more efficient materials opens the door for a green transition in the chemical industry.
