✦ Synopsis

NMR is emerging as a valuable testbed for the investigation of foundational questions in quantum mechanics. The present article outlines the preparation of a class of mixed states, called pseudo-pure states, that emulate pure quantum states in highly mixed solution-state NMR samples. It also describes the NMR observation of spinor 1 behavior in spin nuclei, the simulation of wave function collapse using a magnetic field 2 ( ) gradient, the creation of entangled i.e., Bell pseudo-pure states, and a brief discussion of quantum computing logic gates including the Quantum Fourier Transform. These experiments show that solution-state NMR can be used to demonstrate quantum dynamics at a level suitable for laboratory exercises.
