• Abstract summary: Strong local passivity is a property of multipartite quantum systems from which it is impossible to extract energy locally. If the strong local passive state displays entanglement, it could be possible to locally activate energy density by adding classical communication between different partitions of the system. We report both the first experimental observation of local activation of energy density on an entangled state and the first realization of a quantum energy teleportation protocol using nuclear magnetic resonance on a bipartite quantum system.

• Abstract: Strong local passivity is a property of multipartite quantum systems from which it is impossible to extract energy locally. Surprisingly, if the strong local passive state displays entanglement, it could be possible to locally activate energy density by adding classical communication between different partitions of the system, through so-called "quantum energy teleportation" protocols. Here, we report both the first experimental observation of local activation of energy density on an entangled state and the first realization of a quantum energy teleportation protocol using nuclear magnetic resonance on a bipartite quantum system.

• Second Law of Entanglement Manipulation with Entanglement Battery [41.94295877935867]
  A central question since the beginning of quantum information science is how two distant parties can convert one entangled state into another. It has been conjectured that entangled state transformations could be executed reversibly in an regime, mirroring the nature of Carnot cycles in classical thermodynamics. We investigate the concept of an entanglement battery, an auxiliary quantum system that facilitates quantum state transformations without a net loss of entanglement.

• Harnessing quantum emitter rings for efficient energy transport and trapping [0.0]
  We formulate a quantum optics perspective to excitation energy transport in configurations of two-level quantum emitters. We study a periodic geometry of emitter rings with subwavelength spacing, where collective electronic states emerge. The system gives rise to collective subradiant states that are particularly suited to excitation transport and are protected from energy disorder and radiative decoherence.

• Spin-Dependent Transport Through a Colloidal Quantum Dot: The Role of Exchange Interactions [0.0]
  We combine atomistic electronic structure calculations with quantum master equation methods to study the transport of electrons and holes through strongly confined quantum dots. We find that a competition between the energy spacing between the two lowest quasiparticle energy levels determines the spin states of the lowest two quasiparticle energy levels. The low density of electron states results in a spin singlet being the lowest energy two-electron state whereas, in contrast, the high density of states and significant exchange interaction results in a spin triplet being the lowest energy two-hole state.
