Building Small, Fast and Hot Silicon Spin Qubits

Explore the cutting-edge developments in silicon spin qubits for quantum computing in this comprehensive lecture by Dominik Zumbühl from the University of Basel. Delve into the potential of quantum computers to perform complex tasks exponentially faster than classical computers. Examine the unique properties of qubits based on hole spins in 1D Ge/Si nanowires, including their strong and electrically tunable spin-orbit interaction. Learn about the impressive ability to manipulate Rabi frequency, driven coherence time, and Landé g-factor using small gate voltage changes. Discover the concept of a spin-orbit switch and its applications in optimizing qubit performance. Investigate the approach towards the strong driving regime, where spin-flipping times can be as short as ~1 ns. Gain valuable insights into the latest advancements in quantum computing technology and their potential impact on future computational capabilities.
