Systems and methods are disclosed for increasing a nuclear spin polarization of a target compound. In accordance with such systems and methods, a first non-thermal equilibrium nuclear spin polarization can be imparted to at least one source atom of a source compound, the source atom having a nuclear gyromagnetic ratio of at least 12 megahertz per tesla (MHz/T). A first solution can be obtained that includes the source compound and a target compound. The at least one source atom can be present in a source concentration of at least 0.1 molar (M) in the first solution. A second non-thermal equilibrium nuclear spin polarization of at least 0.01% can be imparted to the at least one target atom of the target compound via a nuclear Overhauser effect (NOE) transfer of the first non-thermal equilibrium nuclear spin polarization to the at least one target atom.

Systems and methods for quantum computing

Systems and methods are disclosed for increasing a nuclear spin polarization in a target compound. Nuclear spin polarization can be increased by obtaining the target compound or a precursor of the target compound.

Systems and method for quantum computing

A method for generating a nuclear magnetic resonance spectrum of nuclear spin moments of a sample includes a static magnetic field permeating the sample, and a detection spin moment with a detection region surrounding the latter. The detection region extends at least partly into the sample. The method also includes an antenna element for radiating in frequency pulses for influencing the nuclear spin moments and radio-frequency pulses for influencing the detection spin moment, where a polarization step involves polarizing at least one portion of the nuclear spin moments along the magnetic field to form a longitudinal magnetization, where a transfer step involves converting the longitudinal magnetization (M) into a transverse magnetization (M) by radiating in a frequency pulse (F) with a 90&#xb0; flip angle, wherein a detection step involves radiating in a sequence of radio-frequency pulses onto the detection spin moment and subsequently detecting a signal (') of the transverse magnetization (M) present in the detection region and storing the signal as detection result in a list. The detection step is carried out a number of times repeatedly in succession, wherein the polarization step and the transfer step and also the detection steps are carried out.
