A team of scientists led by Prof. Dipankar Home from Bose Institute, Kolkata, in collaboration with researchers from the University College London and the University of Southampton, UK, has proposed an experimental study to test the validity of quantum theory for macroscopic objects. This research aims to bridge the gap between quantum mechanics and classical Newtonian mechanics for larger-scale objects, a longstanding challenge in physics. The team's innovative approach involves using a quantum pendulum with a nanocrystal of silica suspended by lasers in a vacuum chamber to detect measurement-induced disturbances. By observing the behavior of this quantum pendulum, the researchers hope to push the boundaries of quantum theory beyond microphysical objects and explore the realm of macroscopic quantumness. The experiment, if successful, could lead to a better understanding of quantum principles for massive objects and pave the way for the development of high-precision quantum sensors essential for cutting-edge quantum technologies. Prof. Home and his collaborators envision that this research will not only shed light on fundamental quantum issues but also have practical applications in the near future, potentially revolutionizing the field of experimental physics.
