Spins, when placed in a strong magnetic field, have nondegenerate eigenstates that allow encoding quantum information. Nuclear spin ensembles in bulk samples at room temperature not only retain quantum coherences for long durations but are also amenable for elaborate quantum control via nuclear magnetic resonance (NMR) techniques. After a brief overview on Quantum Information and NMR, I will describe some of our recent experiments using star-topology spin-registers.
T. S. Mahesh did his bachelors and masters in Physics at JCBM College (Kuvempu University) and Mangalore University respectively. He has worked with Prof. Anil Kumar for his Ph.D in Physics at IISc, Bangalore. He carried out post-doctoral research with MIT-Cambridge fellowship at MIT, USA with Prof. David G. Cory and later as a Humboldt Fellow with Prof. Dieter Suter at Dortmund University, Germany. He has been a recipient of DST Swarnajayanthi fellowship and also has received the award instituted by National Magnetic Resonance Society in the year 2014. His research interests spin around Nuclear Magnetic Resonance Spectroscopy and Quantum Information Processing.
