By storing electronic excitation energy in a symmetry-protected dark state living in a decoherence-free subspace, one can protect the charged EQB from environment-induced energy losses, thereby making it a promising platform for long-term energy storage. To illustrate the key physical principles and potential functionality of this concept, we consider an open quantum network model of a para-benzene-like structure.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Circa 2019 Robust quantum energy storage devices are essential to realize powerful next-generation batteries.
