Abstract: Disclosed herein are methods and apparatuses for sequencing nucleic acids using a detection device, the detection device comprising a plurality of spin torque oscillators (STOs) and at least one fluidic channel. In some embodiments of a method, a nucleotide precursor is labeled with a magnetic nanoparticle (MNP), and the labeled nucleotide precursor is added to the fluidic channel of the detection device. It is determined whether at least one of the plurality of STOs is generating a signal. Based at least in part on the determination of whether the at least one of the plurality of STOs is generating the signal, it is determined whether the labeled nucleotide precursor has been detected.

Abstract: A method for quantum spin amplification includes spin-polarizing an ensemble of quantum spins in an initial spin state to generate a transversely-polarized sensing spin state. The quantum spins identically have an upper energy state and a lower energy state. The sensing spin state accumulates a phase shift that transforms the sensing spin state into a phase-accumulated spin state having first and second transverse polarization components. The phase-accumulated spin state is transformed into an intermediate spin state by rotating the first transverse polarization component into a longitudinal polarization component of the intermediate spin state. The ensemble is then coupled to an auxiliary mode, during which the intermediate spin state evolves such that the second transverse polarization component is amplified into an amplified transverse polarization. This amplified transverse polarization is then measured.

Abstract: An apparatus comprises one or more substrates and one or more coils. At least one of the coils is configured to produce a first magnetic field that induces eddy currents in a conductive target, which generates a reflected magnetic field. One or more magnetic field sensing elements supported by the one or more substrates detect the reflected magnetic field. A conductive support structure supports the one or more substrates. The support structure includes a gap in an area adjacent to the one or more coils so that the support structure does not generate a reflected magnetic field in response to the first magnetic field.

Abstract: A sensing probe may be formed of a diamond material comprising one or more spin defects that are configured to emit fluorescent light and are located no more than 50 nm from a sensing surface of the sensing probe. The sensing probe may include an optical outcoupling structure formed by the diamond material and configured to optically guide the fluorescent light toward an output end of the optical outcoupling structure. An optical detector may detect the fluorescent light that is emitted from the spin defects and that exits through the output end of the optical outcoupling structure after being optically guided therethrough. A mounting system may hold the sensing probe and control a distance between the sensing surface of the sensing probe and a surface of a sample while permitting relative motion between the sensing surface and the sample surface.

Abstract: The disclosed technology generally relates to computation devices, and more particularly to majority gate devices configured for computation based on spin waves. In one aspect, a majority gate device comprises cells that are configurable as spin wave generators or spin wave detectors. The majority gate device comprises an odd number of spin wave generators, and at least one spin wave detector. The majority gate device additionally comprises a waveguide adapted for guiding spin waves generated by the spin wave generators. The spin wave generators and the at least one spin wave detector are positioned in an inline configuration along the waveguide such that, in operation, interference of the spin waves generated by the spin wave generators can be detected by the at least one spin wave detector. The interference of the spin waves corresponds to a majority operation of the spin waves generated by the spin wave generators.
