DESCRIPTION: Prof. Michael R. Wasielewski\,\nAbstract:\nWe will describe
  recent work from our laboratory that focuses on using photo-driven proces
 ses to generate entangled electron spins in molecular materials targeting 
 applications in quantum computing\, communications and sensing. We will ex
 plain how ultrafast photogeneration of electron-hole pairs within covalent
  electron donor-acceptor systems results in two entangled spins having suf
 ficiently long coherence times to perform CNOT gate operations and to tele
 port a prepared quantum state on a third spin to one of the spins comprisi
 ng the entangled pair. We will also describe recent work using photogenera
 ted entangled spin pairs to serve as a molecular electric field sensor. Fi
 nally\, we will show how chirality-induced spin selectivity (CISS) strongl
 y influences the spin dynamics of photogenerated electron-hole pairs in d
 onor-chiral bridge-acceptor molecules. Exploiting CISS affords the possib
 ility of using chiral molecular building blocks to control electron spin s
 tates for quantum information applications.\n\nBio:\nMichael R. Wasielews
 ki is the Clare Hamilton Hall Professor of Chemistry and Applied Physics 
 at Northwestern University. He is also Director of the Center for Molecula
 r Quantum Transduction\, a US-DOE Energy Frontier Research Center\, the In
 itiative for Quantum Information Research and Engineering\, and the Triene
 ns Institute for Sustainability and Energy at Northwestern. He received hi
 s B.S.\, M.S.\, and Ph.D. degrees from the University of Chicago and was a
  postdoctoral fellow at Columbia University. His research has resulted in 
 over 800 publications and focuses on light-driven processes in molecules a
 nd materials\, solar energy\, quantum information science\, molecular opto
 -electronics\, ultrafast optical spectroscopy\, and time-resolved electron
  paramagnetic resonance spectroscopy. He is member of the US National Acad
 emy of Sciences and the American Academy of Arts and Sciences and is the r
 ecipient of numerous awards for his work.\n
