Physicists have entangled and measured two tangible objects at the quantum level for the first time.

For the new work, the authors used two small objects, which, by the standards of the quantum world, have

gigantic in size. They are several tens of microns in length and width, and several hundred nanometers in thickness.

They can be seen with a microscope and touched with tweezers. 

Through trial and error, scientists were able to findthe optimal length of microwave pulses, the interactions with which entangled both resonators at the quantum level, despite the fact that each of them consisted of more than a trillion individual atoms.

If you look at each drum separately, thenit will seem to you that both resonators are simply heated to high temperatures. If you observe them together, you will notice that the vibrations of their membranes and changes in position were synchronized in a way that could only be explained by the fact that both objects were entangled with each other at the quantum level. 

John Teufel, NIST Research Fellow 

As Teufel notes, his team conducted over 10 thousand repeated tests of this experiment to confirm that an invisible quantum connection between the reels really exists. 

New development can improve the performance of variousultra-sensitive sensors and measuring instruments that use entangled objects to increase the accuracy of measurements. Also, quantum drums can be used as long-term storage for information on quantum computers and exchange nodes of quantum networks.
