Wolter, Benjamin (Data de defensa: 2018-02-26)
One of the grand challenges of modern science is to image chemical reactions and biological functions while they are taking place. To realize these molecular movie, experimental techniques need to resolve the relevant ...
Sridhar, Susmita (Data de defensa: 2016-10-05)
Polarization gating imaging is a popular and widely used imaging technique in biomedical optics to sense tissues, deeper volumes, and also selectively probe sub-superficial volumes. Due to the "polarization memory" effect ...
Piga, Angelo (Data de defensa: 2020-03-30)
During the past two decades, thanks to the mutual fertilization of the research in quantum information and condensed matter, new approaches based on purely quantum features without any classical analog turned out to be ...
Prettico, Giuseppe (Data de defensa: 2013-01-18)
Quantum Information Theory (QIT) studies how information can be processed and transmitted when encoded on quantum states. Practically, it can be understood as the effort to generalize Classical Information Theory to the ...
Beduini, Federica A. (Data de defensa: 2015-11-03)
This thesis analyses the effects of two-photon interference in a polarisation squeezed state under two different points of view: on one hand, it presents a new method to obtain the temporal wavefunction of a state of two ...
Vallés Marí, Adam (Data de defensa: 2017-02-14)
The work presented in this thesis, mostly experimental, is based on three main pillars: the concepts of entanglement, Bell's inequalities and coherence. Entanglement is a very special type of correlation that can exist ...
Akgul, M. Zafer (Data de defensa: 2021-02-11)
Due to the continuously increasing energy demand and the environmental concerns about climate changes raised by international community, alternative energy resources have been put under intense investigation for the past ...
Liga, Shanti Maria (Data de defensa: 2023-03-22)
(English) The availability of energy is a fundamental ingredient for the development of society. However, the intense consumption of fossil fuels as an energy resource since the second industrial revolution has caused a ...
Raventós Ribera, David (Data de defensa: 2019-04-15)
Understand and tame complex quantum mechanical systems to build quantum technologies is one of the most important scientific endeavour nowadays. In this effort, Atomic, molecular and Optical systems have clearly played a ...
Alloing, Mathieu (Data de defensa: 2014-05-28)
In this thesis, we report experimental evidence of a "gray" condensate of excitons, as predicted theoretically by M. Combescot et al. Most importantly, the condensate is characterized by the macroscopic population of dark ...
Huwer, Jan Henning (Data de defensa: 2014-01-29)
One promising approach for future quantum networks is the combination of strings of trapped ions as quantum-information processors with entangled photon pairs produced by spontaneous parametric down conversion (SPDC) to ...
Woessner, Achim (Data de defensa: 2017-05-11)
Plasmons are charge oscillations coupled to electromagnetic radiation. One of their most intriguing properties is their deep subwavelength confinement resulting in strongly enhanced light-matter interaction. Metal plasmons ...
Barcons Ruiz, David (Data de defensa: 2023-07-11)
(English) Graphene has revolutionized the field of condensed matter physics over the last two decades, emerging as an outstanding research platform. This is because graphene electrons behave as massless Dirac fermions, ...
Schmidt, Peter, 1989- (Data de defensa: 2019-04-16)
Transition metal dichalcogenides (TMDs) are semiconducting layered materials that can be isolated up to the limit of a single atomic layer. Next to graphene, they are some of the most intensively studied materials within ...
Aloy López, Albert (Data de defensa: 2020-07-16)
Entanglement and non-local correlations give rise to unprecedented phenomena with no classical analogue. As a result, they have settled themselves as fundamental properties in the study of quantum many-body systems, as ...
Heller, Lukas (Data de defensa: 2023-11-06)
(English) Quantum memories are devices that are able to store photonic quantum states and entanglement. Future quantum networks, which could enhance cybersecurity through quantum key distribution, improve the precision in ...
Hesp, Niels Caspar Herman (Data de defensa: 2021-10-20)
Nano-optics studies the behaviour of light on the nanoscale. In particular, it probes the interaction of light with objects, often of nanometre-size, and reveals fine details of the material's optical properties. Optoelectronics ...
Kramarenko, Mariia (Data de defensa: 2023-03-24)
(English) To mitigate the energy and climate crisis we are already facing and address the increasing energy consumption, it is essential to foster energy transition strategies. The energy transition success largely depends ...
Morales Dalmau, Jordi (Data de defensa: 2019-02-15)
Suspensions of gold nanorods (GNRs) are emerging as potential drugs to address some of the limitations in traditional biomedical sensing,imaging and therapy. They are inorganic nanoparticles with good biocompatibility, ...
Torre Carazo, Gonzalo de la (Data de defensa: 2015-09-23)
Physics has two main ambitions: to predict and to understand. Indeed, physics aims for the prediction of all natural phenomena. Prediction entails modeling the correlation between an action, the input, and what is subsequently ...
