Cabrera Córdova, César Raymundo (Data de defensa: 2018-10-10)
In this thesis, we report on the design and construction of a quantum simulator experiment using quantum gases in Spain. This experiment exploits mixtures of the three isotopes of potassium, which give access in an original ...
Dawid Lekowska, Anna Maria (Data de defensa: 2022-09-20)
(English) Quantum many-body physics poses a substantial computational challenge resulting from the exponential growth of the wave function complexity and many non-trivial correlations encoded in it. Studying many-body ...
Colangelo, Giorgio (Data de defensa: 2016-12-16)
This thesis describes quantum measurements of an ensemble of cold rubidium-87 atoms. We extend the covariance matrix formalism to spin-1 systems, including effects of decoherence, losses due to probing and atom number ...
Kutluer, Kutlu (Data de defensa: 2017-10-23)
A photonic quantum memory (QM) is a device that has the capability of storing a quantum state of light and retrieving back after a controlled time. It is an important element in quantum information science and is, among ...
Lucivero, Vito Giovanni (Data de defensa: 2016-10-14)
Nowadays there is a considerable progress in optical magnetometry and spin noise spectroscopy, which use magnetically-sensitive atomic ensembles and optical read-out, approaching the limits set by quantum mechanics. In ...
Raissi, Zahra (Data de defensa: 2020-10-08)
Studying entanglement is essential for our understanding of such diverse areas as high-energy physics, condensed matter physics, and quantum optics. Moreover, entanglement allows us to surpass classical physics and ...
Padrón Brito, María Auxiliadora (Data de defensa: 2021-04-08)
Photons are good candidates for carrying quantum information because they are very stable particles: they interact weakly with the medium and barely with each other. However, this has drawbacks when you want to process ...
Almeida, Jessica Oliveira de (Data 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 (Data 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 (Data 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 (Data 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 (Data 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 ...
