Physical review letters

Wolfowicz G, Maier-Flaig H, Marino R, Ferrier A, Vezin H, Morton JJ, Goldner P.
PMID: 25978214
Phys Rev Lett. 2015 May 01;114(17):170503. doi: 10.1103/PhysRevLett.114.170503. Epub 2015 Apr 30.

Interfacing between various elements of a computer--from memory to processors to long range communication--will be as critical for quantum computers as it is for classical computers today. Paramagnetic rare-earth doped crystals, such as Nd(3+):Y2SiO5(YSO), are excellent candidates for such...

J Am Chem Soc. 2005 Nov 09;127(44):15417-28. doi: 10.1021/ja0518225.

Long-lived spin-correlated pairs were generated by laser irradiation of naphthalene (NAP) occluded as intact molecule within non-Brønsted acidic MnZSM-5 zeolites with MnSiO(2))(96-n)(AlO(2)n formula per unit cell. The laser UV photoionization generates primary NAP.+-electron pair as a fast phenomenon. These...

Metalloenzymes use earth-abundant non-noble metals to perform high-fidelity transformations in the biological world. To ensure chemical efficiency, metalloenzymes have acquired evolutionary reactivity-enhancing tools. Among these, the entatic state model states that a strongly distorted geometry induced by ligands around...
