Quantum batteries It's still a thing of the future despite some progress in recent years. The promise of a radical revolution in energy storage motivates researchers around the world. The team has now made great progress.
The idea behind quantum batteries is this Super absorption. Molecules absorb light, similar to solar cells. Through so-called superposition, several wavelengths, here the wavelengths of light, can interfere without disturbance. This means that they can enhance each other without interfering with each other.
Bigger battery, shorter charging time
In a quantum battery, this ensures that as the number of molecules increases, the number of molecules also increases Speed Increases their rate of absorption of light. This would include the battery Increase capacity Loading faster too. This was first proven in 2022.

Researchers in National Cheng Kung University In Taiwan, a practical method for charging quantum batteries has now been identified. That's why ION was created Cobbettif superimposed by one cavity trafficker. The qubit in this case is the battery. Cavitation works like a freighterThis is done by reflecting specific wavelengths that the ion absorbs and charges them.

The researchers ran the qubit through an experimental setup several Loading cavities. Different wavelengths of light worked there. In the second experimental setup, it was just the qubit a A charging cavity in which the optical wavelengths are not separated is transmitted.
Lossless download
The latter turned out to be particularly effective. By doing so, they not only confirmed that a quantum battery could work. At least in theory they showed “Ideal charging phenomenonThis means that all available energy can be stored without loss.
The researchers worked with IBM Quantum Platform. Your proof of concept must be scalable, and thus also work in large batteries containing more than one qubit. The results were published in the specialized journal Physical review research published.
However, quantum batteries have not yet been used. The big hope is that the technology will work in the long term Electric cars To use that Charged in a flash can become. Another advantage is that There are no rare materials Essential for such batteries. The necessary foundations for this are currently being laid, but practical implementation still requires a long time.
