SUMMARY:ICFO | VICTOR CHAMPAIN
CLASS:PUBLIC
DESCRIPTION:Spins in semiconducting materials hold great promise for large-
 scale quantum computing due to their compactness and compatibility with st
 andard CMOS processes. However\, scaling spin-based quantum processors pre
 sents a key challenge: maintaining qubit fidelity as system size increases
 . In state-of-the-art devices\, heating effects - primarily caused by diss
 ipation from control pulses - have emerged as a limiting factor. Notably\,
  systematic drifts in the Larmor frequency of spins have been observed fol
 lowing microwave excitations\, revealing a complex temperature dependence 
 whose origin remains elusive.\nIn this presentation\, I will discuss the f
 undamental properties of hole spins in silicon\, with a focus on their spi
 n-orbit interaction. I will examine the thermal susceptibility of hole spi
 ns and explore its potential electrical origin. Finally\, I will demonstra
 te how to study dissipation associated with qubit manipulation in quantum 
 dot arrays. These insights are crucial for mitigating thermally induced de
 phasing in spin-based quantum architectures.
