Micromasers as Quantum Batteries

Explore the concept of micromasers as quantum batteries in this 28-minute lecture by Giuliano Benenti from the PCS Institute for Basic Science. Delve into the emerging field of quantum technologies and the importance of energy storage in quantum mechanical systems. Discover how micromasers, utilizing a beam of qubits to charge the electromagnetic field in a cavity, serve as an excellent model for quantum batteries. Learn about achieving highly excited, pure, and effectively steady states of cavity modes through coherent qubit charging, even in ultra-strong coupling regimes of field-matter interaction. Examine the stability of these features against qubit coherence loss and the effects of counter-rotating terms in interaction Hamiltonians. Gain insights into cutting-edge research on quantum batteries and their potential applications in the rapidly evolving landscape of quantum technologies.
