dc.description.abstract	An ensemble of nuclear spin pairs under certain conditions is known to exhibit singlet state lifetimes much longer than other nonequilibrium states. This property of singlet states can be exploited in quantum information processing for efficient initialization of quantum registers. Here we describe a general method of initialization and experimentally demonstrate it with two-, three-, and four-qubit nuclear spin registers.	en_US
