Creation of entangled states in coupled quantum dots via adiabatic... C. Creatore, R. T. Brierley, R. T. Phillips,
... The excited states of this subset include spatially entangled states that could be identified spectrally. The robustness of ARP, then, allows a pulse to be constructed that transfers these pairs into their entangled excited states, without exciting the others. Thus, as shown in Fig. 3, the entanglem ...

If a nongoal state is discovered then the current state is expanded by applying a successor function, generating a new set of states. The choice of which state to expand is determined by a search strategy. In ...
