Scientists from Kolkata's Bose Institute, along with collaborators from University College London and the University of Southampton, have embarked on a groundbreaking experiment to test the boundaries of quantum theory on massive objects. While quantum mechanics is a well-established framework describing the behavior of particles at microscopic scales, its applicability to larger, macroscopic objects remains an open question. This research seeks to address this fundamental gap, exploring the transition from quantum to classical physics.

   Led by Prof. Dipankar Home and his team, the experiment involves the use of lasers to suspend and oscillate a silica nanocrystal (a tiny glass bead) within the focal point of a parabolic mirror. This setup allows researchers to observe and measure disturbances in the system, induced by quantum mechanics. The goal is to demonstrate quantum behavior in objects significantly larger than previously studied, thereby extending the domain of validity of quantum principles.

   The findings could have profound implications for both theoretical physics and practical applications. On one hand, they provide insights into the nature of quantum-classical boundaries, addressing questions about the extent to which quantum mechanics applies to macroscopic objects. On the other hand, the research paves the way for innovations in quantum technology, including the development of high-precision quantum sensors.

   This study builds on quantum theory’s rich legacy of breakthroughs, from the famous double-slit experiment that demonstrated wave-particle duality, to modern technologies like semiconductors and quantum computing. By exploring how quantum mechanics governs larger systems, the Bose Institute’s experiment could redefine our understanding of the universe and unlock new technological advancements.
