Researchers at the University of Nottingham developed 3D-printed titanium surfaces with intricate textures (hexagonal pockets and conical protrusions) that bounce unwanted gas particles away from quantum sensors. These textured surfaces enhanced surface-based vacuum pumps by up to 3.8 times, with simulations suggesting potential ten-fold improvements. The innovation helps quantum sensors maintain the ultra-high vacuum conditions needed for accurate measurements by passively removing nuisance particles, potentially reducing reliance on bulky pumps and making quantum technologies more portable.
