A thin device triggers one of quantum mechanics’ strangest and most useful phenomena. An ultrathin invention could make future computing, sensing and encryption technologies remarkably smaller and more powerful by helping scientists control a strange but useful phenomenon of quantum mechanics, according to new research recently published in the journal Science.

Quantum Entanglement realized between Distant Large Objects

Quantum entanglement realized between distant large objects
Light propagates through the atomic cloud shown in the center and then falls onto the SiN membrane shown on the left. As a result of interaction with light the precession of atomic spins and vibration of the membrane become quantum correlated. This is the essence of entanglement between the atoms and the membrane.

A team of researchers at the Niels Bohr Institute, University of Copenhagen, have succeeded in entangling two very different quantum objects. The result has several potential applications in ultra-precise sensing and quantum communication and is now published in Nature Physics.

Entanglement is the basis for quantum communication and quantum sensing...

Physicists at the Institute of Science and Technology Austria (IST Austria) have invented a new radar prototype that utilizes quantum entanglement as a method of object detection. This successful integration of quantum mechanics into our everyday devices could significantly impact the biomedical and security industries. The research is published in the journal Science Advances.

Quantum entanglement is a physical phenomenon where two particles remain inter-connected, sharing physical traits regardless of how far apart they are from one another...

Engineers have demonstrated for the first time that it’s possible to connect a network of sensors through quantum entanglement. The experiment opens a door to unprecedented levels of sensitivity in GPS navigation, medical imaging and astronomy.

Your phone’s GPS, the WiFi in your house and communications on aircraft are all powered by radio-frequency waves, or waves, which carry information from a transmitter at one point to a sensor at another. The sensors interpret this information in different ways. For example, a GPS sensor uses the angle at which it receives an RF wave to determine its own relative location. The more precisely it can measure the angle, the more accurately it can determine location.

In a paper pu...
