Foundations of quantum physics


Quantum Mechanics was formulated in its most primitive form more than one hundred years ago. Its improvement over the decades led to a better understanding of the physical world, followed by a myriad of technological applications, some of them fully developed (e.g. the laser) and others yet to come (e.g. quantum computation). For such implementations to be possible, a close connection to foundational aspects is mandatory: purely quantum effects should be identified and studied. To this end, we deal with paradigmatic examples covering the ondulatory effects of quantum evolution, the manipulation and trapping of quantum particles and the resources of quantum computation.
