Quantum Entanglement Between Objects Becomes a Reality

If there’s any way to surpass the speed of light, the answer lies in quantum entanglement. Furthermore, it doesn’t even have to violate Albert Einstein’s statement that light travels at the maximum allowed speed throughout the Universe. Quantum entanglement means passing information from one object to another extremely quickly.

The Niels Bohr Institute from the University of Copenhagen is home to a recent scientific achievement that will make history. A team of scientists belonging to this institute managed to entangle two quantum objects.

Entanglement between a mechanical oscillator and a cloud of atoms

Each of the two structures behaves like a tiny magnet. These are two different entities, and the entanglement was possible by connecting them using photons. While atoms can be processing quantum information, vibrating dielecting membrane (or the mechanical oscillator) can be useful when it comes to the storage of quantum information.

Professor Eugene Polzik, who led the scientists’ work, explains just how great the achievement is:

With this new technique, we are on route to pushing the boundaries of the possibilities of entanglement. The bigger the objects, the further apart they are, the more disparate they are, the more interesting entanglement becomes from both fundamental and applied perspectives. With the new result, entanglement between very different objects has become possible.

One of the members of the research team raises the awareness about the fact that Quantum mechanics is a pretty tricky field, as it gives wonderful new technologies, but can also limit precision measurements that otherwise would have been easy.

Quantum mechanics is well-known for its unique and peculiar set of laws that are governing its realm, which means that it’s totally different from the way classical mechanics work. Reconciling the two fields is currently one of the greatest challenges in science.
