A group of scientists carried out theoretical studies, the results of which showed that the matrix consisting of nanoscale batteries can be charged much faster than each such battery individually. This phenomenon is the result of so-called collective quantum interactions, which form the basis of a relatively new field - quantum thermodynamics. This area is concerned with the study of how quantum effects affect the laws of traditional physics that define such fundamental quantities as energy, work, and t.

The overwhelming majority of studies related to the practical use of the phenomena of quantum mechanics are aimed at the transfer of quantum information and its processing in the depths of the developed quantum computer systems. And only in isolated cases are conducted studies demonstrating the advantages of using quantum effects in other areas, in particular, in thermodynamics. Only recently has it been demonstrated how the phenomenon of quantum entanglement can allow more work to be done by using energy extracted from one nanoscale device, a kind of "quantum battery".

In new research, scientists have shown that quantum phenomena allow not only more efficient use of energy, with their help, it is also possible to increase the capacity and reduce the charging time of the above-mentioned quantum batteries. Moreover, this process does not require the presence of quantum entanglement, although this requires a number of conditions required to create quantum entanglement.

"We demonstrated that it is quite possible to organize a quantum interaction between two or more bodies without involving quantum entanglement in this phenomenon," researchers at Monash University, Australia write, "The resulting so-called quantum advantage is proportional to the number of people involved in All this bodies, quantum nano-sized batteries in this case ".

The quantum advantage provided by interactions also has its limits, which determine the minimum possible charging time of the batteries due to quantum effects. The main limiting factor is the quantum velocity factor, the maximum rate of quantum processes, which determines both the limits of quantum-thermodynamic processes and the speed of future quantum computers.

"Quantum bits, qubits of quantum computers, which are ions or atoms, can also be considered as tiny quantum storage batteries, in relation to which the results of our research can be applied," write the researchers. "And our main goal is to It was to use the quantum advantage in systems with a finite number of involved bodies wherever possible. This, in turn, can lead to the emergence of a number of fantastic technologies, ranging from tiny batteries, comparable in capacity to large batteries, nanomachines capable of performing a large amount of work and much more ".
