13:00 Oxide 2D-electron gas with engineered function properties for quantum physics and applications

Oxide 2D-electron systems are characterized by extraordinary functional properties, including large Rashba-like spin-orbit coupling and unconventional superconductivity. In this contribution I will give an overview of possible application of oxide 2DEGs as topological and spin-orbit qubits

09:15 Spontaneous 3D photonic crystals from ferroelectric domains in KTN:Li

We discuss our experimental exploration of how spontaneous photonic crystals form supported by polarization supercrystals (PSCs) in near-transition potassium-lithium-tantalate-niobate (KTN:Li) and its implications for topologically-protected photonic waveguides and memory bits.

10:15 From single superconducting components to integrated qubit circuits: Vertical Josephson junctions, low-loss superconducting resonators and high-kinetic inductance films

The performance of single superconducting circuital components fundamentally limits the performance of complex multi-qubit circuits. We therefore optimise the design and microfabrication of elementary building blocks, maximising control and reproducibility and minimising microwave losses.
