Scientists have discovered how the performance of a quantum computer can be affected by its surrounding environment. The study, published in the latest issue of the journal Science, will help engineers to better understand how to integrate quantum components into a standard office computer – moving us one step closer to a future of quantum computing.
The collaborative team from the London Centre for Nanotechnology, University College London (UCL), the Paul Scherrer Institute/ETH in Switzerland and the Universities of Chicago and Copenhagen, have shown how its environment can radically alter the behaviour of a quantum computer, an effect which is not present for conventional computers of the type that exist now on our desktops.
Professor Gabriel Aeppli of UCLs Dept of Physics and the Director of the London Centre for Nanotechnology says: "One of the most important questions in natural sciences is whether quantum mechanics is relevant to everyday experience. The famous puzzle of whether Schroedingers cat is dead or alive is the most graphic representation of this question, traditionally considered an academic point of no real practical import.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
