Superabsorption in an organic microcavity: Toward a quantum battery

Abstract

In a major step toward the development of a quantum battery, superabsorption has been achieved in an organic microcavity.

Demonstration of dynamical control of three-level open systems with a superconducting qutrit

“…The current scheme can be applied to the QB [58][59][60][61][62][63][64][65][66][67][68][69][70][71][72]. We notice there is a recent study for stabilizing the energy of the QB by dark states [92], and realized in an experimental system including a microcavity enclosing a molecular dye [93]. Additionally, there is a recent relevant experiment optimizing the compromise between charging time and stored energy of quantum batteries [94].…”

Materials and devices for fundamental quantum science and quantum technologies

“…Indeed, it is difficult to imagine a "quantum society" where computing, communications, and sensing will be carried out by relying on the principles of quantum mechanical laws while energy will be provided by systems ruled by standard electrochemical laws and 200-years old designs. There are three classes of energy-related quantum devices, which are currently being mainly studied by academia and that will need to gradually be evaluated and adopted by industry: i) quantum heat engines for energy production [187][188][189][190][191][192][193][194], ii) quantum batteries [195][196][197][198][199][200][201][202][203][204][205] and supercapacitors [206] for energy storage, and iii) quantum energy lines [207] for energy transfer. Research and development on all these aspects may lead to a profound "cultural" and technological revolution in how energy is produced, stored, and conveyed.…”

Quantum advantage in charging cavity and spin batteries by repeated interactions

“…One of the prime candidates for experimental proofs-of-principle is the Dicke-model battery [71][72][73][89][90][91], in which an ensemble of qubits is charged by a collectively coupled oscillator mode (see also related proposals in waveguide QED set-ups [92,93]). Recent efforts in cavity-and circuit-QED have brought about the first results [94,95].…”
