Research interests: spin and magnetic resonance based quantum information processing
Professor Jonathan Baugh is working toward the physical realization of quantum information processors in solid-state systems, using the property of spin to encode and manipulate quantum information.
Baugh believes that the power of quantum information lies in the mathematical structure of quantum mechanics, in which the non-classical concepts of superposition, entanglement and quantum parallelism arise. He is a proponent of taking the ideas and concepts of quantum information theory and implementing them in the laboratory, and sees this as a crucial aspect of the development of quantum technologies that will dominate in the 21st century.
Baugh completed his PhD in Physics in 2001 at the University of North Carolina at Chapel Hill. Part of his PhD research on nuclear dipole-dipole interactions in nanoscale-confined fluids was published in Science in 2001. Baugh was a Post-Doctoral Fellow at the Institute for Quantum Computing (IQC) from 2002-2005, and a Visiting Researcher and Japan Society for the Promotion of Science (JSPS) Fellow at Tokyo University in the Department of Applied Physics in 2006-7. Baugh is a Professor in the Department of Chemistry and is cross-appointed to Physics and Astronomy at the University of Waterloo.

Developing scalable approaches to building quantum processors
Dr. Baugh joined Institute for Quantum Computing (IQC) as a faculty member in 2007, where he is a group leader in the Coherent Spintronics Lab. The aim of the lab is to develop scalable approaches to building quantum processors based on electron and nuclear spins. Current projects focus on coherent control of single electron spins in quantum dots (e.g. artificial atoms/molecules), hyperfine coupled electron-nuclear spin systems, single molecule magnets and solid-state nuclear magnetic resonance.
Developing techniques for scalable Quantum Information Processing (QIP)
The goal of the Coherent Spintronics Lab’s experimental program is to develop prototypes and quantum control techniques necessary for scalable QIP. Particular focus is on using the particle property of spin to encode quantum information in a robust way. Realizing spin-based quantum bits (qubits) in solid-state systems offers a technologically attractive path to scalable quantum devices; this approach is reminiscent of (and builds on) the semiconductor microelectronics industry, and benefits from cutting edge device technologies now being developed based on novel nanomaterials such as semiconductor nanowires and carbon nanotubes. The research group is establishing a comprehensive program aimed at addressing the fundamental and technical challenges to realizing quantum building block devices. This research will expand fundamental scientific knowledge and create new platforms for technological innovation.
