Accanto, Nicolò (Date of defense: 2016-06-16)
Nanophotonics aims to understand and control the interaction of light-matter at the nanometer scale. Boosted by the development of nanotechnology and nanofabrication, nanophotonics is a thriving research field, with ...
Weber, Peter (Date of defense: 2016-12-02)
In recent years, mechanical resonators based on graphene have attracted considerable interest as nanoelectromechanical systems (NEMS). Graphene NEMSs allow for exceptional properties such as high mechanical strength, high ...
Colangelo, Giorgio (Date of defense: 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 ...
Singh, Anshuman (Date of defense: 2017-11-11)
Optical nanoantennas confine light on the nanoscale, enabling strong light-matter interactions with potential for ultra-compact optical devices. Apart from the direct applications in optical nanoscopy and sensing, nanoantennas ...
Rieländer, Daniel (Date of defense: 2016-11-24)
This PhD thesis is in the scope of experimental quantum communication. It deals with correlated photon pairs of which one photon is stored in a solid state device, while the other photon is at telecom wavelength. Quantum ...
Verdeny Vilanova, Ione (Date of defense: 2016-10-13)
Intracellular transport plays an essential role in a wide variety of fundamental cellular processes required to maintain the internal regulation and organization of cells. Different types of cargos such as organelles, ...
So, David (Date of defense: 2016-10-19)
The ubiquity of solar energy conversion technology is an exciting target which we aspire for in this century. Colloidal quantum dot (CQD) solar cells are an attractive platform, being low-cost and allowing facile control ...
Salazar Serrano, Luis José (Date of defense: 2016-10-13)
Weak Value Amplification (WVA) is a signal enhancement technique proposed in 1988 by Aharonov, Albert, and Vaidman that has been widely used to measure tiny changes that otherwise cannot be determined because of technical ...
Sridhar, Susmita (Date of defense: 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 ...
Lucivero, Vito Giovanni (Date of defense: 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 ...
Cousin, Seth Lucien (Date of defense: 2016-09-12)
Attosecond science investigates the realm of processes that happen in fleetingly short passages of time. One attosecond to one second, is what one second is to the age of the universe! Advances in lasers and specifically ...
Kuffer, Dominik (Date of defense: 2016-06-13)
In the last decade, two-dimensional (2D) materials have attracted attention both in the nascent field of flexible nanotechnology as well as in more conventional semiconductor technol-ogies. Within the rapidly expanding ...
Passaro, Elsa (Date of defense: 2016-05-30)
Quantum information science is a rapidly evolving field both from the theoretical and the experimental viewpoint, motivated by the fact that protocols exploiting quantum resources can perform tasks that are unfeasible in ...
Silva, Francisco José Maia da (Date of defense: 2016-02-29)
Devising new tools that expand our capabilities to sense and manipulate the world enables much of the scientific and technological progress around us. For example, light is increasingly more important as a tool for humanity. ...
Steinlechner, Fabian (Date of defense: 2015-12-14)
The nonlocal correlations of entangled systems are a feature inherent to quantum theory that is fundamentally at odds with our common-sense notions of realism and locality. Additionally, entanglement is an essential resource ...
Beduini, Federica A. (Date of defense: 2015-11-3)
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 ...
Badioli, Michela (Date of defense: 2015-12-04)
Since its discovery in 2004, graphene, a one-atom-thick layer of carbon atoms arranged in a hexagonal lattice, has attracted huge interest from the scientific community due to its extraordinary electronic, mechanical, and ...
Albrecht, Boris (Date of defense: 2015-12-01)
Optical quantum memories are important devices in quantum information science. In particular, they are building blocks of quantum repeater architectures that have been proposed to increase the range of quantum communication ...
Sánchez Bautista, Enrique (Date of defense: 2015-11-26)
High-power, stable, high-repetition-rate, picosecond ultraviolet (UV) sources are of crucial importance for a variety of applications, such as atmospheric sensing, spectroscopy or optical data storage. Further, precise ...
