Quantum batteries have garnered significant attention as a novel
energy storage paradigm, leveraging quantum phenomena such as coherence,
entanglement, and squeezing to outperform classical counterparts. While
a substantial body of research has focused on finite-dimensional
systems, particularly spin-based and qubit-based models, the potential
of bosonic systems, such as harmonic oscillators, remains underexplored.
This research aims to bridge this gap, emphasizing the unique advantages
offered by continuous-variable setups, including scalability, and
compatibility with realistic physical systems, in particular quantum
optics and materials.
