Almeida, Jessica Oliveira de (Fecha de defensa: 2022-07-28)
Quantum optics experiments are currently the most advanced techniques to under- stand, verify and simulate quantum phenomena. However, to access all the perfor- mance available in quantum states of light, one needs to ...
Abellán Sánchez, Carlos (Fecha de defensa: 2018-06-19)
Randomness is one of the most intriguing, inspiring and debated topics in the history of the world. It appears every time we wonder about our existence, about the way we are, e.g. Do we have free will? Is evolution a result ...
Hauke, Philipp Hans-Jürgen (Fecha de defensa: 2013-04-05)
Many outstanding problems in quantum physics, such as high-Tc superconductivity or quark confinement, are still - after decades of research - awaiting commonly accepted explanations. One reason is that such systems are ...
León Montiel, Roberto de Jesús (Fecha de defensa: 2014-09-30)
For many years, the fields of quantum optics and biology have rarely shared a common path. In quantum optics, most of the concepts and techniques developed over the years stand for systems where only a few degrees of freedom ...
Camphausen, Robin (Fecha de defensa: 2023-04-12)
(English) Entangled photon pairs can enhance optical imaging capabilities. Phase imaging allows detecting fine detail of transparent samples without potentially invasive fluorescent labelling, and here entanglement enables ...
