Problem A semiconductor quantum-dot is modeled as a cube with side L as shown in the figure below. The potential inside the quantum-dot is V = 0 while the potential outside is V = V.. Z V = V. L y V = 0 L L For the following questions, model an electron inside the quantum-dot as an electron in an infinite quantum-dot well (V = V. = 0). (a) The quantum-dot will be used in the design of lasers for the telecommunications industry where a laser operating at 1 = 1.55 um is required to minimize absorption in fiber optics. What must be the size of the quantum-dot? (b) Quantum computing requires the fabrication of a semiconductor qubit. A qubit requires that only two energy states are available to the electron confined inside the quantum structure. Considering that the potential outside the quantum-dot above is finite with V = V0 = 1 eV, can this quantum-dot be used to implement a qubit? Quantitatively justify your answer.
