 \, postdocs\, students\, group leaders\, and PIs are welcome to join us.\n
 \nTITLE: QSOLID Project: Current Status and Development Logic\n\nABSTRACT
 : \nIn this talk\, I will present the current status and development logi
 c of the QSOLID project\, which aims to build a scalable superconducting q
 uantum computing platform. A central focus is our 10-qubit architecture\, 
 which we use as a controlled engineering demonstrator rather than a mere p
 roof of principle. Even at this scale\, material limitations\, readout-cha
 in imperfections\, and amplifier-induced constraints manifest themselves i
 n a non-negotiable way.\nParticular emphasis will be placed on speeding up
  measurement and initialization\, which remains a key challenge for scalab
 le quantum computing. We experimentally demonstrate a dispersive measureme
 nt scheme for superconducting qubits that simultaneously measures the qubi
 t state and actively resets the readout resonator to its initial state\, e
 nabling faster measurement cycles without residual photon population.\nI w
 ill also discuss our progress on novel coherent materials and fabrication 
 strategies for Traveling-Wave Parametric Amplifiers (TWPAs)\, and analyze 
 their impact on the overall quantum efficiency of the readout chain.\nThe 
 underlying message is intentionally conservative: before claiming hundreds
  of qubits\, one should first learn how to control\, calibrate\, and read 
 out ten of them accurately and reproducibly.\n\nReferences:\nM. Jerger et

 Master’s degree cum laude in quantum radio-physics in Moscow Physical Te
 chnical Institute (Moskau\, Russische Föderation) in 1997. During his doc
 toral research in Innsbruck University he worked on experiments with singl
 e trapped barium ion and a single photon. Pavel performed first experiment
 s on quantum-limited motion detection and feedback for which he obtained a
  PhD degree cum laude. After a two-years postdoc in ETH Zürich and 2 year
 s in Ulm\, he worked as senior research assistant in Karlsruhe Institute o
 f Technology for 4 years during 2009-2013 on investigations of superconduc
 ting qubits and hybrid quantum systems. In 2013 he joined the department o
 f experimental physics in Universität des Saarlandes as assistant profess
 or. The research topic of his group was mainly focused on quantum microwav
 e photonics and metrology.
