1. 1. Chemoreception of a Two-Dimensional Cell with Multilayer Diffusion

   University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

   Author : Steffi Schijf; [2023]
   Keywords : biophysics; chemoreception; receptors; multilayer diffusion; diffusion; Physics and Astronomy;

   Abstract : Previously, Berg and Purcell found an expression for the diffusion current of particles into a set of receptors in their paper Physics of Chemoreception. These receptors were assumed to be uniformly distributed on a spherical cell's surface and the receptors where idealized as circular patches. READ MORE

3. 2. Active stabilisation of a micro-sized fibre cavity using tilt locking to enable quantum operations on single ions

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Jannek Hansen; [2021]
   Keywords : Quantum computation; optical cavity; microcavity; locking; tilt locking; cavity stabilization; Gaussian-Hermitian modes; quantum computer; higher-order transverse modes; Physics and Astronomy;

   Abstract : In this thesis, the tilt locking scheme is applied to create an error signal that monitors length changes in a fibre-based microcavity. To find a robust and precise locking technique is an essential step towards quantum operations on single rare-earth ions doped in microcrystals. Quantum computing and information is a frontier of modern physics. READ MORE

4. 3. Optical Study of Micro-Resonators with G-centers as an Active Medium

   University essay from KTH/Tillämpad fysik

   Author : Baptiste Lefaucher; [2021]
   Keywords : G-center; Silicon Photonics; Micro-Resonators Optics; Laser; Photo-Luminescence Spectroscopy; G-center; Kiselfotonik; Mikroresonatoroptik; Laser; Fotoluminescensspektroskopi;

   Abstract : The G-center has recently been identified as the first deterministic single-photon punctual emitter isolated in silicon. This discovery is of great interest for largescale quantum technologies, due to the abilities of silicon in terms of integration and scalability. READ MORE

5. 4. A Fabry–Pérot Cavity for Rare-Earth-Ion-Doped Nanocrystals

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Andre Nüsslein; [2019]
   Keywords : Quantum Computer; Rear Earth Ions; Cavity; Laser; Cavity Quantum Electrodynamics; QED; Solidworks; Physics and Astronomy;

   Abstract : This thesis work contributes to the effort of detecting single rare earth ions doped into crystals, an operation crucial for the development of rare earth quantum computer hardware. Doping crystals with rare earth elements, their trivalent ions substitute some of the crystal’s original bonds. READ MORE

6. 5. "Fat" Nanobeam-Waveguide Resonator for Suppressing Spectral Diffusion in InGaAs Quantum Dots

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Qinda Guo; [2019]
   Keywords : Physics and Astronomy;

   Abstract : The coherent coupling of photons to solid state emitters is one of the building blocks for future quantum technology. However, one of the main sources for non-perfect or even strongly reduced coherence of the photons is charge noise which introduces energy shifts during or in between the photon emission events.
