Multimode advantage in continuous variable quantum battery

Energetics of a pulsed quantum battery

“…Here we seek to provide a simple yet explanatorily powerful model of a bipartite quantum battery driven by a short laser pulse. We model our battery charger and battery holder as quantum harmonic oscillators, such that our theory contributes to the emerging body of work on (a) E-mail: c.a.downing@exeter.ac.uk (corresponding author) quantum continuous variable batteries [21][22][23][24][25]. Within an open quantum systems approach, we provide compact expressions describing the energetic and power performance of the battery, as well as brief formulae for the maximum amount of work which can be extracted [1,26] and for various desirable charging times.…”
