1. Localized and extended states in finite-sized mosaic Wannier-Stark lattices
University essay from KTH/Tillämpad fysikAbstract : Anderson localization occurs when an otherwise conductive solid becomes insulatingdue to a sufficiently large degree of disorder in the medium. The electron band energy(as a function of disorder) at which this transition between extended and localizedelectron states occur is called the mobility edge (ME) and is energy-dependent only in3-dimensional systems.

2. Communication and Error Correction via Polarisation of Single Photons and Time Ordering
University essay from KTH/Tillämpad fysikAbstract : This research study aims to investigate the capacity of single photons to carry information through polarization and time ordering and proposes a protocol called Beyond Pulse Position Modulation (BPPM) to improve photon-based communication reliability over longer distances with limited power. Such a protocol may be used in any communication scenario where energy efficiency is important, e. READ MORE

3. Towards a tunable, wide-band acoustic transducer operating in the quantum regime.
University essay from KTH/Tillämpad fysikAbstract : In the past decade we have seen fast development of new quantum technologies that promise to revolutionise communications and computing. Many different routes are explored to physically implement such quantum technologies. Among others, we can mention superconducting circuits, spin-based devices and photonic devices. READ MORE

5. Nonlinear mode coupling and parametric amplification with superconducting kinetic inductance
University essay from KTH/Tillämpad fysikAbstract : We investigate the resonant characteristics of superconducting meandering nanowires to design a nonlinear kinetic inductance traveling-wave parametric amplifier. The devices are patterned out of 15 nm thick NbTiN films. They consist of a coplanar waveguide, that shrinks into 100 nm wide meandering nanowires. READ MORE
