Researchers cooled and sent a sodium cluster about 8 nm in diameter (≈170,000 amu) through an interferometer to reveal wave-like interference, marking the largest object observed in quantum superposition and showing quantum mechanics applies to sizeable nanoparticles despite decoherence in larger systems.
Physicists demonstrated a macroscopic quantum superposition by sending a beam of 7,000-atom sodium nanoparticles through a narrow slit, which produced an interference pattern and set a new record for the size of objects observed in quantum states; the result points toward future experiments with larger, even biological, molecules in quantum superpositions.
Researchers demonstrate quantum interference of sodium clusters containing thousands of atoms (mass >170 kDa) in a near-field Talbot–Lau interferometer using three UV gratings, achieving fringe visibilities that align with quantum predictions and yielding a macroscopicity value of μ = 15.5—the highest reported to date. This shows the quantum superposition principle persists at this unprecedented mass/size and provides a platform to test macrorealist modifications of quantum mechanics, with future work aiming to reach even larger masses (MDa range) as experimental techniques improve.
