Dept. of Materials Science and Engineering Spring Seminar Series: Michael Wasielewski

Description

Michael Wasielewski, a professor of chemistry in the Northwestern University, will give a talk titled "Photogeneration and Control of Molecular Electron Spin Qubits for Quantum Information Applications" for the Department of Materials Science and Engineering.

Abstract:

We will describe recent work from our laboratory that focuses on using photo-driven processes to generate entangled electron spins in molecular materials targeting quantum information applications. We will show how ultrafast photogeneration of electron-hole pairs within covalent electron donor-acceptor systems results in two entangled spins having sufficiently long coherence times to perform quantum gate operations and to teleport a prepared quantum state on a third spin to one of the spins comprising the entangled pair. We will describe how chirality-induced spin selectivity strongly influences the spin dynamics of photogenerated electron-hole pairs in donor-chiral bridge-acceptor molecules. Finally, we will show how molecular diradicals can serve as versatile surrogates for nitrogen vacancy defect centers in diamond.
