If there is a way to beat the speed of light, the answer lies in quantum entanglement. Moreover, it is not even necessary to violate Albert Einstein’s statement that light travels at the maximum speed allowed throughout the Universe. Quantum entanglement involves passing information from one object to another extremely quickly.
The Niels Bohr Institute at the University of Copenhagen is home to a recent scientific achievement that will make history. A team of scientists belonging to this institute succeeded in entangling two quantum objects.
Entanglement between a mechanical oscillator and a cloud of atoms
Each of the two structures behaves like a tiny magnet. They are two different entities, and the entanglement was possible by connecting them with the help of photons. While atoms can process quantum information, the vibrating dielectric membrane (or mechanical oscillator) can be useful for storing quantum information.
Professor Eugene Polzik, who led the work of the scientists, explains how formidable this achievement is:
With this new technique, we are on the way to pushing the limits of the possibilities of entanglement. The larger the objects, the more distant they are, the more disparate they are, the more interesting the entanglement becomes from both a fundamental and an applied point of view. With the new result, entanglement between very different objects became possible.
One of the research team members is raising awareness that quantum mechanics is quite a tricky field, as it offers wonderful new technologies, but can also limit precision measurements that would otherwise have been easy.
Quantum mechanics is well known for its unique and peculiar set of laws that govern its field, which means that it is totally different from how classical mechanics work. Reconciling the two fields is currently one of the greatest challenges in science.
