Scientists Have Set a Limit for Quantum Entanglement

A recent research paper published in the Nature Communications, scientists have revealed that they have managed to force quantum entanglement to extreme level of acceleration. Interestingly, the experimented particles were firm even though they were accelerated to 30 times of Earth’s gravity and scientists have claimed that the findings from the research might have a big impact on modern physics.

In case you didn’t know, Quantum Entanglement is one of the most interesting research area of quantum mechanics where to particles share the same existence. As a result, if one of the particle is affected in any way, it affects the other one even though the other particle might be a long distance away.

Although researchers have known for a long time that the entanglement is real, Einstein’s theory of relativity cannot explain the phenomenon. As it’s essential to observe aspects of both quantum and classical physics simultaneously to bridge the gap between classical and quantum physics, researchers used entangled particles to high accelerations described by relativity.

In order to achieve the goal, the scientists mounted a source of entangled photon pairs in a crate and then dropped them from a height of 12 meters to achieve zero gravity during a free-fall. After wards, they attached to the arm of a spinning centrifuge and then accelerated to up to 30g. In order to observe the effect of such acceleration, detectors mounted to the crate and these detectors revealed that the pairing actually held firm within the milli-g (drop tower) and hyper-g (centrifuge) conditions.

Scientists associated with the research said, “Our results show that quantum entanglement is unaffected by non-inertial motion to within the resolution of our test-system.”

“This represents the first experimental effort exposing a genuine quantum system to milli-g and hyper-g, and extends the experimental regime in which quantum effects can be said to exist in harmony with relativity.”

“If entanglement were too fragile, quantum experiments could not be carried out on a satellite or an accelerated spacecraft, or only in a very limited range.”

“Our next challenge will be to stabilize the setup even more, in order for it to withstand much higher accelerations. This would enhance the explanatory power of the experiment even further.”
