    Aloy López, Albert (Date of defense: 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 ...

    Exploring quantum memory schemes in cold atoms for quantum repeaters 

    Heller, Lukas (Date of defense: 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 ...

    Exploring the applications and limitations of location-based social network data in urban spatiotemporal analysis 

    Yang, Liya (Date of defense: 2021-09-27)

    Nowadays, the widespread utilization of intelligent mobile and located-embedded services extends the border of social network sites (SNS) to physical-spatial space. The appearance of SNS changes our daily life meanwhile ...

    Exploring the potential usage of underused urban space: Hajj sites in Mecca as case study 

    Imam, Ayman Amin (Date of defense: 2017-07-20)

    The term Underused Urban Spaces (UUS) refers to spaces within urban areas that have become unused, or that are being used to a lesser degree than they could or should be. The emergence of such spaces has therefore encouraged ...

    Exploring the topical structure of short text through probability models : from tasks to fundamentals 

    Capdevila Pujol, Joan (Date of defense: 2019-09-26)

    Recent technological advances have radically changed the way we communicate. Today’s communication has become ubiquitous and it has fostered the need for information that is easier to create, spread and consume. As a ...

    Exploring twisted bilayer graphene with nano-optics 

    Hesp, Niels Caspar Herman (Date of defense: 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 ...

    Exponentiated weibull fading channel model in free-space optical communications under atmospheric turbulence 

    Barrios Porras, Ricardo (Date of defense: 2013-05-17)

    Free-space optical (FSO) communications is drawing increasing attention as a promising technology to overcome bandwidth shortage, of an evermore crowded wireless marketplace. Currently radio-frequency (RF) technology ...
