Physicists coaxed a beam of sodium nanoparticles (~7,000 atoms each) to behave as a single quantum wave, producing an interference pattern and setting a new record for macroscopic quantum states, hinting at future experiments that could place biological molecules in quantum states.
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 propose a top-down approach to building a large quantum register using a Bose-Einstein condensate (BEC) of excitons. By generating and controlling macroscopic quantum states of BEC consisting of millions of identical excitons, they aim to overcome the challenges of short-lived phenomena and ultra-low temperatures typically associated with quantum computing. The use of a superfluid BEC state can prevent quantum decoherence and enable faster quantum gate operations. The proposed system shows promise for scalability and offers computational capabilities and redundancy for quantum error correction.
