Recent advancements in quantum technology have led Chinese researchers to achieve a remarkable feat: they successfully stored light for an impressive 4035 seconds, which is over 67 minutes. This breakthrough, conducted at the Beijing Academy of Quantum Information Sciences, surpasses the previous record of just a few seconds. The implications of this discovery could be significant for the fields of quantum computing and information transfer.

The challenge of storing light has long puzzled scientists due to the rapid movement of photons, the particles that make up light. Traditional methods struggled to maintain the integrity of light signals for extended periods. However, the researchers found a solution by converting light signals into sound waves, which are easier to store and later convert back into light. This innovative approach allowed them to retain the information for much longer than before.

The material used in this experiment, single-crystal silicon carbide, proved to be highly effective due to its low internal losses and stability at low temperatures. This discovery not only enhances the performance of quantum computers but also opens up new possibilities for secure communication networks. The researchers aim to further improve storage times and integrate their findings with other quantum technologies, potentially revolutionizing the digital landscape in the coming years.
