Resumen:
Bound and resonance states of a two-electron quantum dot are studied using a variational expansion with real basis-set functions. The two-electron entanglement von Neumann entropy is calculated as a function of the quantum-dot size at both sides of the critical size, where the ground bound state becomes a resonance unbound state. The use of von Neumann entropy is proposed as a method for the determination of the energy of a resonance.
