We consider the quantum dot system initially in an incoherent mixture of the two electron-spin states. We show that the application of regular delayed and partially overlapping pulses can lead to initialization. In addition, if initially delayed, partially overlapping, and simultaneously switched off pulses are applied, the initially incoherent mixture can be changed to a specifically designed coherent superposition state. We also find that due to the initial conditions of the studied quantum system, the proposed methods work for different pulse orderings.engjournal articlehttps://doi.org/10.1063/1.5079412https://aip.scitation.org/doi/10.1063/1.5079412open access537.531530.145535Coherent controlQuantum coherenceElectromagnetic pulseOptical fieldQuantum computingAdiabatic processDark stateQuantum mechanical systems and processesQuantum dotsQuantum opticsElectromagnetismoÓptica (Física)Teoría de los quanta2202 Electromagnetismo2209.19 Óptica Física2210.23 Teoría Cuántica
