Suppressing the coffee-stain effectThe ‘coffee-stain’ effect is a well-known effect in physics and daily life: a dark-coloured edge remains when a fluid, containing particles, evaporates. This is caused by an ‘avalanche’ of particles moving to the outer edge, UT scientists showed in an earlier publication. In inkjet and 3D printing, this is an undesired effect. The effect can be suppressed by modifying the surface using an oily layer, researchers now show in the Proceedings of the National Academy of Sciences of the USA (PNAS).Read more
Fifty perfect photons for 'quantum supremacy'Fifty is a critical number for quantum computers capable of solving problems that ‘classic’ supercomputers cannot solve anymore. Proving ‘quantum supremacy’ requires at least 50 so-called ‘qubits’. For quantum computers working with light, it is equally necessary to have at least 50 photons. And what’s more: these photons have to be perfect, or else they will worsen their own quantum capabilities. It is this perfection that makes it hard to realize. Not impossible, however: scientists of the University of Twente demonstrate that by proposing modifications of the crystal structure inside existing light sources. Their findings are in Physical Review A.Read more
