 s quantum information technology matures and becomes more complex\, so do 
 the needs for interconnecting disparate quantum subsystems (computers\, ne
 tworks\, sensors) into larger quantum networks. Thus\, developing reliable
  quantum interconnects (QuICs) – from chip- to continental-scale\, is
  emerging as one of the central goals for quantum information science and 
 technology. I will describe our activities aimed at realization of two imp
 ortant QuICS: quantum repeaters (QR) and quantum transducers (QT). Our QRs
  rely on silicon-vacancy (SiV) color center in diamond\, a leading quantu
 m memory platform\, essential for realization of long-distance quantum net
 works [1]. In addition to their excellent spin and optical properties\, Si
 Vs feature large strain susceptibility [2] which has resulted in emergence
  of the field of quantum phononics. Here\, phonons could be used to contr
 ol SiVs [3-5] as well as to realize chip-scale QuICs. I will also discuss
  our work on thin film lithium niobate (TFLN) photonic platform [6] that c
 an be used to control spectral [7] and temporal [8] properties of photons 
 emitted by SiVs. Finally\, QTs based on TFLN [9\, 10] will also be present
 ed. These devices can enable realization of networks of quantum computers\
 , connected with low loss and low noise optical communication channels. \
 n\nBio:\nMarko Lončar is Tiantsai Lin Professor of Electrical Engineering
  at Harvard's John A Paulson School of Engineering and Applied Sciences (S
 EAS)\, and chair of Electrical Engineering area. Lončar received his Dipl
 oma from University of Belgrade (R. Serbia) in 1997\, and PhD from Caltech
  in 2003 (with Axel Scherer)\, both in Electrical Engineering. After compl
 eting his postdoctoral studies at Harvard (with Federico Capasso)\, he joi
 ned Harvard faculty in 2006. Lončar is expert in nanophotonics and nanofa
 brication\, and his group has done pioneering work in the field of quantum
  and nonlinear nanophotonics. In particular\, Lončar is recognized for hi
 s work on the development of diamond and thin film lithium niobate nanopho
 tonic platforms. Lončar has co-authored more than 250 manuscripts in top 
 scientific journals and has given more than 300 invited talks and seminars
 . He has received NSF CAREER Award in 2009\, Sloan Fellowship in 2010\, Ma
 rko Jarić Foundation Award in 2020\, and Microoptics Conference Award in 
 2023. In recognition of his teaching activities\, Lončar has been awarded
  Harvard University Levenson Prize for Excellence in Undergraduate Teachin
 g (2012)\, and has been named Harvard College Professor in 2017. Lončar i
 s Fellow of Optical Society of America and IEEE\, as well as Senior Member
  of SPIE. He is co-founder of HyperLight Corporation (Cambridge\, MA)\, VC
  backed startup commercializing lithium-niobate technology developed in hi
 s lab.\n\nRegistration highly recommended. A Zoom link will be available
