2,000 atoms were made to be together at a time at two places

The new experiment demonstrated a bizarre quantum effect from the double-slit experiment at an unprecedented scale.

We all have known that there is always a wave associated with matter, whatever it is, and due to quantum superposition waves can exist at two places at once but still, now we haven’t found a chunk of matter existing at two places simultaneously.

For the first time, in a new work published in Nature science journal, an international team of researchers made it possible to make 2000 atoms together to occupy two places at a time.

To perform the double-slit experiment with a large no. of atoms together researchers built a machine that could fire a beam of molecules (some more than 25000 times the mass of hydrogen atoms) through series of gratings and multiple stilted sheets. It was 6.5 feet long beam that was big enough to account for heat jostling.

When the machine was switched on, the molecules showed an interference pattern, which implied that they occupied multiple places at a time. This is a groundbreaking result that would push the mass of matter-wave experiment by an order of magnitude.
