Abstract:

High purity initial states were prepared for nuclear magnetic resonance quantum computing. A chemical reaction involving pure parahydrogen was initiated using a 12 ns laser pulse. The product containes a hydrogen-derived two-spin system with an effective spin-state purity of 0.916. It is observed that the resulting spin state has an entanglement of formation of 0.822 and cannot be described by local hidden variable models.
