Special Issue Information

Dear Colleagues,

As the advent of the heat engine required the development of thermodynamics, the quantum technology ecosystem will require the development of quantum thermodynamic theory. An essential part of this is to understand the properties of energy transfer at the quantum level, including the quantum mechanics of energy storage, charging, and delivery. One of the insights arising out of this research programme is the notion of a quantum battery (QB). QBs represent a new class of energy storage devices that operate on distinctly quantum mechanical principles. In particular, they are driven either by quantum entanglement, which reduces the number of traversed states in the Hilbert space compared to (classical) separable states alone or by cooperative behaviour that increases the effective quantum coupling between battery and source. Up until now, applications of QBs have not been explored in detailed. The idea of a QB is a powerful one, therefore it is imperative that we find out whether it is just a theoretical curiosity or a practical quantum technology. This Special Issue invites researchers to submit original research on the potential applications of QBs.

Because QBs utilise quantum properties, it is reasonable to explore the applications of QB in other quantum technologies, such as quantum computing, communication, sensing. As these technologies are underpinned by the quantum storage and transfer of energy, the applications of QB devices or principles to these technologies may improve their functionality, possibly opening new fields of investigation. For example, does superextensive charging affect quantum computation power? Are their useful applications for a quantum capacitor? Can QB principles be used to further enhance quantum sensing devices? Can QBs replace conventional batteries? Although this ultimately is a question of scalability, it is unlikely that QB will simply replace conventional batteries in the foreseeable future. Instead, QB devices and principles will need to find novel ways to interface with conventional technologies.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Batteries is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

We characterize for the first time the performances of IBM quantum chips as quantum batteries, specifically addressing the single-qubit Armonk processor. By exploiting the Pulse access enabled to some of the IBM Quantum processors via the Qiskit package, we investigate the advantages and limitations of different profiles for classical drives used to charge these miniaturized batteries, establishing the optimal compromise between charging time and stored energy. Moreover, we consider the role played by various possible initial conditions on the functioning of the quantum batteries. As the main result of our analysis, we observe that unavoidable errors occurring in the initialization phase of the qubit, which can be detrimental for quantum computing applications, only marginally affect energy transfer and storage. This can lead counter-intuitively to improvements of the performances. This is a strong indication of the fact that IBM quantum devices are already in the proper range of parameters to be considered as good and stable quantum batteries comparable to state-of-the-art devices recently discussed in the literature.
