Simulating quantum measurements and quantum correlations
(Universitat Politècnica de Catalunya, 2018-01-29)
Tesi
Accés obertThis PhD thesis is focused on the quantum measurement simulability problem, that is, deciding whether a given measurement can be simulated when only a restricted subset of measurements is accessible. We provide an operational ... -
Spontaneous parametric down-conversion sources for generation of atom-resonant quantum light
(Universitat Politècnica de Catalunya, 2018-03-19)
Tesi
Accés obertThis thesis studies different designs of optical parametric oscillators as sources of atom-resonant quantum light resonant with the rubidium D1 line.We analyze the mode structure and filtering techniques in a conventional ... -
Double resonant character in an optical cavity for high performance and stable polymer solar cells
(Universitat Politècnica de Catalunya, 2018-03-23)
Tesi
Accés obertSolution-processed thin film solar cells emerged as very promising photovoltaic technologies suitable for a low cost roll-to-roll upscale production. Such thin film character also ensures lightweight and flexibility for ... -
Novel methods for plasmonic nanoparticles imaging inside cells using dark-field microscopy
(Universitat Politècnica de Catalunya, 2018-02-22)
Tesi
Accés obertThe potential impact of noble metal nanoparticles (NPs) in diverse fields, particularly medicine, is tremendous. However, before NPs can be routinely used in clinical practices, it is fundamental to comprehensively study ... -
Electron re-collision dynamics in strong mid-IR fields for diffraction imaging of molecular structure and its fragmentation
(Universitat Politècnica de Catalunya, 2018-02-26)
Tesi
Accés obertOne 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 ... -
Superresolution fluorescence microscopy with structured illumination
(Universitat Politècnica de Catalunya, 2017-11-29)
Tesi
Accés obertThe resolution of a conventional fluorescence microscope image is diffraction limited which achieves a spatial resolution of 200nm lateral and 500nm axial. Recently, many superresolution fluorescence microscopy techniques ... -
Coherent sensing of magnetic waveforms with spin-squeezed atoms
(Universitat Politècnica de Catalunya, 2017-12-14)
Tesi
Accés obertOptical magnetometers use magnetically-sensitive atomic ensembles and optical read-out to detect the amplitude of magnetic fields. They have become the most sensitive instruments for measuring low-frequency magnetic fields ... -

Quantum information with black boxes : lifting protocols from theory to implementation
(Universitat Politècnica de Catalunya, 2017-10-17)
Tesi
Accés obertAccording to recent estimates, 10^18 bytes of data are generated on a daily basis around the globe. Our information society urges for radical solutions to treat such data deluge. By exploiting fundamental key elements of ... -
New systems for quantum nonlinear optics
(Universitat Politècnica de Catalunya, 2017-10-19)
Tesi
Accés obertPhotons travelling through free space do not interact with each other. This characteristic makes them perfect candidates to carry quantum information over long distances. On the other hand, processing the information they ... -
Quantum memory protocols for photonic solid-state devices
(Universitat Politècnica de Catalunya, 2017-10-23)
Tesi
Accés obertA 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 ... -
Strong-field processes in atoms and polyatomic molecules
(Universitat Politècnica de Catalunya, 2018-01-23)
Tesi
Accés obertIn this thesis, we develop a general theory to describe the dynamics of electrons that are ionized when an atom or molecule is exposed to a strong low frequency laser field. Our approach extends and improves the well-established ...
