• Abstract: We propose a novel approach for optimization of charging of harmonic oscillators (quantum batteries) coupled to a harmonic oscillator (charger), driven by laser field. We demonstrate that energy transfer limitations can be significantly mitigated in the presence of catalyst systems, mediating between the charger and quantum batteries. We show that these catalyst systems, either qubits or harmonic oscillators, enhance the amount of energy transferred to quantum batteries, while they themselves store almost no energy. It eliminates the need for optimizing frequency of the charging laser field, whose optimal value in the bare setting depends on coupling strengths between the charger and the batteries.

  We propose and analyze a universal method to obtain fast charging of a quantum battery by a driven charger system using controlled, pure dephasing of the charger. The battery displays coherent underdamped oscillations of energy for weak charger dephasing, while the quantum Zeno freezing of the charger energy at high dephasing suppresses the rate of transfer of energy to the battery.

  A model that allows a laser to shine on a QHO charger that interacts with a QHO battery is considered. For a fixed laser field amplitude, the battery can store more energy when tuned with the frequency of the global charger-battery system. The charging process of QHO in the simplified model is faster than the charging process of the catalytic (non-catalytic) battery.

This hybrid method tackles with arbitrarily strong electron-phonon coupling without increasing the number of required qubits and quantum gates. We benchmark the new method by applying it to the paradigmatic Hubbard-Holstein model at half filling, and show that it correctly captures the competition between charge density wave and antiferromagnetic phases.

  We use reinforcement learning to optimize the charging process of a Dicke battery. We find that the extractable energy (ergotropy) and quantum mechanical energy fluctuations (charging precision) can be greatly improved. Notably, the collective speedup of the charging time can be preserved even when nearly fully charging the battery.
