aThe energy-level diagram of167Er3+: Y2SiO5. The Zeeman upper states are frozen under our experimental conditions. See text for details.bThe full absorption spectrum after AFC preparation for 1936 ns storage time. Arrow AFC pump: central frequency of the AFC pump laser, denoted as 0...
As shown in Fig.2, the energy level diagram of different spin configurations, optical excitations and different relaxation and decay processes were included. We listed the Liouvillian operators that describe quantum jumps (incoherent processes) below. The superoperators constructed by the Lindblad operato...
Figure 1. Electron energy diagram illustrating the formation of a potential well by sandwiching a layer of narrow gap semiconductor material (B) between two wider gap layers (A). The optical properties of semiconductors are usually considered in terms of transitions of electrons between quantum mech...

Figure 1. Diagram showing the three possible configurations of a three-level atom according to the permitted transitions between its levels. Figure 2. (Left) 3D plot of the entropy of entanglement as a function of the coupling parameters 𝜇12μ12 and 𝜇23μ23, the maximum value of the ...
Figure 5. (a) Energy level structure of InAs/GaAs QD; (b) Schematic diagram of neutral exciton and charged exciton. When the InAs/GaAs QD is excited through up the band, the photon energy of the excitation light is larger than the forbidden band width of GaAs around the QD. The elect...
Fig. 16. Diagram, proposed mechanism and characterized results of double elements doped GQDs. (a) and (b) show UV–vis absorption and proposed energy-level diagram of S and N co-doped GQDs (S,N-GQDs) through solvothermal synthetic approach [152]; (c) Schematic illustration of the prepared...
Quantum computing holds the promise of solving some of our planet's biggest challenges - in the areas of environment, agriculture, health, energy, climate, materials science, and more. For some of these problems, classical computing is increasingly challenged as the size of the system grows. ...
