Spin coherence
WebSpin–Lattice Relaxation Times ( T1) Spin coherence times are extremely important for potential application of the molecular spin centers in quantum computation. In physics, two wave sources are coherent if their frequency and waveform are identical. Coherence is an ideal property of waves that enables stationary (i.e., temporally or spatially constant) interference. It contains several distinct concepts, which are limiting cases that never quite occur in reality but allow an understanding of the physics of waves, and has become a very important concept in quantum physics. More generally, coherence describes all properties of the correlation
