Coherent Spin-Valley Oscillations in Silicon 

Abstract: Electron spins in semiconductor quantum dots are excellent qubits because they have long coherence times and are compatible with advanced semiconductor manufacturing techniques. Coherent manipulation of single electron spins generally involves rapidly oscillating real or effective magnetic fields, which drive magnetic resonance. In this talk, I will describe a new technique for manipulating electron spins in silicon that relies only on dc voltage pulses.  This method offers a new way to manipulate electrons in semiconductors and reveals a new family of spin qubits.

Bio: John Nichol is an associate professor in the Department of Physics and Astronomy at the University of Rochester. He earned a PhD from the University of Illinois at Urbana-Champaign and a BA from St. Olaf College. Nichol investigates the quantum mechanics of nanoscale objects, especially individual electrons in semiconductor quantum dots. Nichol's current research focuses on improving the coherence of electron spin qubits using new materials and control methods, exploring new ways to transfer quantum information between distant spin qubits, and many-body quantum coherence in spin chains. Nichol is the recipient of an NSF CAREER award and a Google Research Scholar Award.
