Integrated circuits containing all our electronic devices, Solar panelsmagnetic resonance machines, The lasers or the atomic watches that allow the human being to measure time with an unprecedented precision would not be possible without the knowledge he has given us Modern Quantum Theory. And, of course, without this model we would not have Quantum computers. Objectively, and it is not at all an exaggeration, quantum physics is present in much of modern technology.
During the last five years several research groups, such as the PSL Research University (University of Recherche Paris Sciences et Lettres), which resides in Paris (France), or that of the University of Pisa, in Italy, have tried to use the basic principles of quantum mechanics to point A new generation of batteries. And the results are getting little by little. This is its starting point: they pursue to use overlap, entanglement and superabsorption to tear down the limitations that electrochemical batteries currently impose.
The quantum storage of energy is an ideal that is increasingly closer
The main difference between quantum batteries and conventional electrochemicals is that the latter depend on chemical reactions, while quantum devices seek to store energy in the quantum states of some particles, such as, for example, photons. It seems complicated, and it is, but the really important thing for users is that quantum batteries on paper can be loaded almost instantaneously, they will have a much higher energy density, and, in addition, their degradation will be minimal as the load cycles pass.
Quantum batteries can store energy in a superposition of multiple energy states simultaneously
It sounds wonderful. So much, in fact, that seems science fiction. However, it is very important that, as we have just seen, let’s not overlook that their principle of operation will be, if they finally come to fruition, very different from that of conventional electrochemical batteries. Existing theoretical proposals argue that quantum batteries They can store energy in an overlap of multiple energy states simultaneously, which should allow them to deliver a much greater energy density.
In addition, your theory load will be much faster, even almost instantaneous, due to the collective quantum effects of the quantum units that make them up. The most amazing thing in this field is that the higher the capacity of the quantum battery, the faster it will load. It is an intuitive characteristic, it is true, but it is possible precisely thanks to the collective quantum effects I just talked about. However, this is not all. And it is that on paper the degradation that these batteries will experience during energy transfer will be minimal, so your useful life will be much greater than that of conventional batteries. Perhaps, even, almost eternal if we compare it with the longevity of the human being.
So far all the work that researchers had carried out in this area had condensed in purely theoretical models, but this panorama has just changed. And it is that several scientists from the universities that I have mentioned in the second paragraph of this text have published an article very interesting in which they propose How to make a quantum battery. Your idea is to use superconductor circuits produced with materials that exhibit essentially zero resistance at low temperatures. They have not yet manufactured anything, so it is evident that the hardest work, the experimental, is still pending. But there is no doubt that this proposal invites us to tie the future of quantum batteries with reasonable optimism.
