How to make Chloroform do Addition: classical computing in NMR

Prof. Susan Stepney ( University of York )
As part of a longer term research objective of using the complex structure and dynamics of matter to perform non classical in materio computation, I describe how we have used standard Nuclear Magnetic Resonance (NMR) spectroscopy to perform classical computation.  I describe an approach of using NMR to implement a single universal logic gate, and a circuit of these gates combined in parallel and in sequence that implement other logic gates and a half-adder. I discuss how this approach is just a specific instance applied to a rich parameter space, and discuss how this might be exploited for more sophisticated computations.
