Experimental demonstration of stimulated polarization wave in a chain of nuclear spins

Abstract

A stimulated wave of polarization, which implements a simple mechanism of quantum amplification, is experimentally demonstrated in a chain of four J-coupled nuclear spins, irradiated by a weak radio-frequency transverse field. The "quantum domino" dynamics, a wave of flipped spins triggered by a flip of the first spin, has been observed in fully ${}^{13}$C-labeled sodium butyrate.
