DESCRIPTION:Speaker: Seigo Tarucha\nhosted by Georgios Katsaros \nAbstract:
  Quantum computing (QC) is generally defined as computation based on the p
 rinciples of quantum mechanics\, including superposition\, entanglement\, 
 and parallelism. It is expected to efficiently address complex problems in
  simulation\, optimization\, cryptography\, and machine learning. Research
  on QC has progressed rapidly from theoretical studies to experimental imp
 lementation across various quantum platforms\, such as superconducting cir
 cuits.Among these\, semiconductor-based QC\, though initiated several year
 s later\, has recently attracted increasing attention due to the long intr
 insic coherence times of spin qubits\, their small footprint\, and the com
 patibility of device processing with advanced semiconductor manufacturing 
 technology. Major semiconductor companies\, including Intel\, Imec\, and C
 EA-Leti\, as well as startups\, are now actively developing qubit devices.
 In our work\, we focus on the physics of silicon quantum dot devices that 
 use electron spins as qubits\, exploring both their fundamental properties
  and applications to QC. In this talk\, I will first describe key elements
  in operating spin qubits\, including initialization\, readout\, gate oper
 ations\, entanglement control\, and the effects of noise on spin dynamics 
 that limit performance. I will then review recent challenges in advancing 
 toward scalable QC\, focusing on fault-tolerant operations\, error correct
 ion\, and pathways to large-scale integration.
