Will spin-relaxation times in molecular magnets permit quantum information processing?

Abstract:

Using X-band pulsed electron-spin resonance, we report the intrinsic spin-lattice (T1) and phase-coherence (T2) relaxation times in molecular nanomagnets for the first time. In Cr7M heterometallic wheels, with M=Ni and Mn, phase-coherence relaxation is dominated by the coupling of the electron spin to protons within the molecule. In deuterated samples T2 reaches 3μs at low temperatures, which is several orders of magnitude longer than the duration of spin manipulations, satisfying a prerequis...
