1. 1. Robust non-Abelian geometric phases on three-qubit spin codes

   University essay from Uppsala universitet/Materialteori

   Author : Parham Azish; [2024]
   Keywords : Quantum information theory; Holonomic quantum computing; non-abelian systems;

   Abstract : Quantum holonomies are non-Abelian Geometric Phases predominantly observed in adiabatic, non-adiabatic, or measurement-based quantum evolutions. Their significance lies in their potential utility within quantum computing due to their robustness against noise throughout the parameter path. READ MORE

3. 2. Fano Resonances in Time-Dependent Wells

   University essay from Uppsala universitet/Materialteori

   Author : Anton Gregefalk; [2023]
   Keywords : Fano resonance; Floquet scattering; Pumped shot-noise; Linear band tilt; Quadratic band touching; Time periodic Hamiltonian;

   Abstract : Floquet’s theorem, a temporal analogue of Bloch’s theorem, is used for studying a time-dependent potential. With applications in cold atoms on optical lattices, quantum dots and more, there is a growing interest in Floquet engineering exotic materials and phases. READ MORE

4. 3. Spin-Glass Behaviour in Ordered Solids

   University essay from Uppsala universitet/Materialteori

   Author : Erik Karpelin; [2023]
   Keywords : spin-glass; self-induced; variation; Edwards-Andersson; glassy;

   Abstract : The spin-glass is a peculiar magnetic phase, exhibiting non-trivial dynamics at low temperatures, characterized by an continuously evolving state without long-range order. The behavior requires some degree of disorder to occur, often in the way of impurities or random exchange energy between the spins. READ MORE

5. 4. Creating Artificial Quantum Chiral States : Time Evolving Open Spin Chains

   University essay from Uppsala universitet/Materialteori

   Author : Emil Beiersdorf; [2023]
   Keywords : Quantum chirality; chirality; spin interaction; Heisenberg interaction; DM interaction; quantum physics; quantum mechanics; molecular nanomagnet; mathematical physics; theoretical physics; Kvantkiralitet; kiralitet; spinninteraktioner; Heisenberginteraktion; DMinteraktion; kvantfysik; kvantmekanik; molekylär nanomagnet; matematisk fysik; teoretisk fysik;

   Abstract : The discoveries in applications of chirality in various areas of science seem to never cease to emerge. Chirality, being the property that some objects are geometrically distinguishable from their mirror image, is a tiny difference of vast importance. READ MORE

6. 5. Hybrid Microwave Resonator-Nanoscale Conductor Systems

   University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Author : Daniel Larsson Persson; [2023]
   Keywords : Circuit Quantum Electrodynamics; Open Quantum Systems; Gaussian States; Two-Mode Two-Photon Jaynes-Cummings Model; Jaynes-Cummings Model; Lyapunov Equation; Phase-Space Description; Duan Criterion; Entanglement; Light-Matter Interaction; Mean Field; Double Quantum Dot; Harmonic Oscillator; Two-Mode Squeezing; Symplectic Form; GKSL Equation; Lindblad Equation; Physics and Astronomy;

   Abstract : Entanglement is a fundamental aspect of quantum computation and quantum information processes. In this work, we analyse the entanglement of two microwave resonators when connected to a semiconductor double quantum dot. READ MORE
