Scientists of Israeli Institute of Technology use the quantum tunnel to accurately move atoms

2024-11-14 08:55:32

In a breakthrough experiment at the Physics Department of the Israeli Institute of Technology, researchers used optical tweezers to demonstrate the process of transmitting atoms through the quantum tunnel.This new method strategically avoids the capture of atoms in the middle sister -in -law, which is a significant step towards innovative quantum technology.

A new experiment from the Department of Physics of the Israel Institute of Technology shows how to use the quantum tunnel technology of the light to move the atoms between different positions.The study was led by Professor YOAV SAGI and doctoral students from the Institute of Solid Research Institute, and was recently published on Science Advances.

This experiment depends on optical tweezers. This is a powerful tool that uses focalized laser beam capture and manipulation atoms, molecular and even alive cells.Its working principle is as follows: When light interacts with material, it will produce a positive force to be proportional to the light intensity.Although this force is too weak to affect larger objects, it is enough to fix or mobile atom and other micro -particles.The breakthrough invention of Guangye has won the 2018 Nobel Prize in Physics, Arthur Ashkin, which has become an important technology for modern physics.

In the experiments of the Israeli Institute of Technology, researchers arranged three optical tweezers in a row.By adjusting the distance between each pair of adjacent mules, they can dynamically control the rate of quantum tunnels between them.The quantum tunnel is unique to the quantum world, which allows particles to pass through the obstacles that cannot be overcome in classic physics.By dynamically controlling this tunnel rate, the research team successfully moved atoms between the two outer sister -in -law, and it was accurate and efficient.

In addition, the researchers also found that although the possibility of finding them is very low in the middle of the crickets.Looking back at the quantum theory, the particles are described by a wave bag, which can understand the fascinating point of this transfer solution.

In the plan demonstrated in the experiment, waves will cause destructive interference in the intermediate trap, which will cause atoms there.This is the first time that this transfer method is displayed. Researchers believe that this may be an important milestone in the development of a new quantum platform.
