<ul><li>Physicists at Swansea University have proposed a technique to eliminate quantum backaction noise in optical traps for nanoparticles, allowing them to remain suspended undisturbed.</li><li>By making the nanoparticle effectively invisible using a specific setup with a hemispherical mirror and a standing-wave laser, the quantum backaction noise disappears entirely.</li><li>This method involves enhancing the scatter of the nanoparticle to block the flow of information, enabling experiments to be conducted at the Heisenberg limit with minimal noise.</li><li>If successfully demonstrated, this technique could lead to quieter and more precise experiments with ultra-sensitive quantum sensors, offering potential insights into quantum gravity.</li></ul>
