Scientists Built the First Engine Powered by Entanglement—Not Coal or Oil 

Now, scientists from the Chinese Academy of Sciences have developed another method from creating a quantum engine by leveraging another kind of quantum quirk: entanglement. The poster child for all things "quantum," entanglement is the state that occurs when two particles are in superposition, meaning that their information is inextricably linked—no matter the distance between them. The study used calcium atoms in an ion trap, and at its most basic, the engine harnessed a thermodynamic process that occurs when particles transition from initial to highly entangled states. The results of this study were published in the journal Physical Review Letters.


"Our study's highlight is the first experimental realization of a quantum engine with entangled characteristics," Zhou Fei, a co-author of the study, told the state-sponsored media outlet South China Morning Post. "[It] quantitatively verified that entanglement can serve as a type of 'fuel.'"
The website IFLScience describes the process as being similar to a four-stroke engine. First, the atoms absorb photons from a red laser. Then they expand, are coupled with a quantum load, and compress.

This new method didn't improve upon previous quantum engines' conversion efficiency, but the study proved that entanglement can generate useful energy. The team analyzed more than 10,000 experiments using calcium ions and found that increased levels of entanglement created improved mechanical efficiency.
Like quantum computers, these "engines" powered by entanglement only operate at temperatures approaching absolute zero. But further research could make these engines and batteries capable of powering expansive quantum computers and circuits. Only time will tell.

The Craziest Science Moments Of 2024

U Prinstonu su uspeli nekako da crpu energiju koja se generiše rotacijom Zemlje u sopstvenom magnetnim polju. Efekat je na nivou par mikrovolta, ali sve zajedno podseća na perpetuum mobile.

Ako usporimo rotaciju Zemlje ovim putem biće i duži dan i imaću više vremena za spavanje!!!!!!!!!!!
