 Centre\, 200 University Ave West\, Room QNC 1501 Waterloo\,\nON CA N2L 3G1
 \n\nSemiconductor spin qubits are well recognized as a promising platform\
 nfor scalable fault-tolerant quantum computers (FTQCs) because of\nrelativ
 ely long spin coherence time in solid state devices and\nhigh-electrical t
 uneability of the quantum states [1]. In addition\,\nsemiconductors have a
  great potential for applications in quantum\ncommunications because of th
 eir abilities in optical devices.\nTherefore\, especially in quantum repea
 ter applications\, the\nsemiconductor spin qubits provide a route to effic
 iently connect qubit\nmodules or quantum computers via optical fibers and 
 construct global\nquantum networks\, contributing to realize secure quantu
 m\ncommunications and distributed quantum computing [2]. In this talk\, we
 \npresent the physical process enabling the quantum state conversion\nfrom
  single photon polarization states to single electron spin states\nin gate
 -defined quantum dots (QDs) and its experimental demonstration\n[3]. As re
 cent significant achievements\, we discuss that the\nenhancement of the co
 nversion efficiency from a single photon to a\nsingle spin in a quantum do
 t using photonic nanostructures [4].\nFinally\, we present a perspective o
 f high conversion efficiency\nquantum repeater operating directly at a tel
 ecom wavelength based on\nsemiconductor spin qubits.\n\n[1] G. Burkard et
