Abstract: Through discrimination of the scattered signal polarization state, a lidar system measures a distance through semi-transparent media by the reception of single or multiple scattered signals from a scattering medium. Combined and overlapped single or multiple scattered light signals from the medium can be separated by exploiting varying polarization characteristics. This removes the traditional laser and detector pulse width limitations that determine the system's operational bandwidth, translating relative depth measurements into the conditions of two surface timing measurements and achieving sub-pulse width resolution.

Abstract: A time-to-frequency converter transforms an initial single-photon pulse into a transformed pulse such that the temporal waveform of the initial pulse is mapped to the spectrum of the transformed pulse. The time-to-frequency converter includes a dispersive optical element followed by a time lens. The spectrum of the transformed pulse is then measured to determine the arrival time of the initial pulse. The spectrum can be measured using a photon-counting spectrometer that spatially disperses the transformed pulse onto an single-photon detector array. Alternatively, an additional dispersive element can be used with the time-to-frequency converter to implement a time magnifier. The arrival time of the resulting time-magnified pulse can then be measured using time-correlated single-photon counting. This arrival time can then be divided by the magnification factor of the time magnifier to obtain the arrival time of the initial pulse.

Abstract: Technology is disclosed herein that the enhances the measurability of on-chip temperature in a cryogenic quantum computing environment. In an implementation, transceiver circuitry sends a probe signal through a target device. A lumped-element resonator device that is proximate to the surface of the target device interacts with the probe signal and modulates the probe signal. Processing circuitry reads the probe signal through the target device, and responsively measures the resonance frequency of the lumped-element resonator device. The processing circuitry correlates the measured resonance frequency with a temperature and responsively determines the temperature of the target device.

Abstract: Amine substituted morpholino oligonucleotides, other than the classical N,N-dimethylamino PMO analogue, and methods of efficiently synthesizing these oligonucleotides with high yield are provided. Morpholino oligonucleotides having thiophosphoramidate, phosphoramidate, and alkyl phosphoramidate linkers. Chimeras containing unmodified DNA/RNA and other analogs of DNA/RNA can be prepared. These oligonucleotides form duplexes with complementary DNA or RNA that are more stable than natural DNA or DNA/RNA complexes, are active with RNAse H1, and may be transfected into cells using standard lipid reagents. These analogues are therefore useful for numerous applications.

Abstract: A method for forming an oxygen reduction reaction (ORR) catalyst (200, 900) may include providing a carbon (210, 910) supported platinum nanoparticle (220, 920) substrate (Pt/C) (110) and applying a tungsten nitride (WN) film (940) onto the surface of the Pt/C substrate (210, 220, 910, 920) using atomic layer deposition (ALD) (120). The Pt/C substrate (210, 220, 910, 920) with the WN film (940) may then be oxidized at a low temperature (130) and annealed at a high temperature in order to reduce WN to metallic tungsten (W) (140). The metallic W forms a blocking layer (230, 930) over coarse Pt nanoparticles (220, 920) and improves the activity and the durability of the Pt/C catalyst (900, 200) when used in fuel cells or related applications.

Abstract: A photonic-based microwave generator includes a mode-locked laser that generates an optical pulse train, a feedback photodiode that samples the optical pulse train, and a servo amplifier that processes the photodiode output into a servo signal. The servo signal controls the mode-locked laser to suppress relative intensity noise on the optical pulse train. The microwave generator may also include a microwave photodiode for converting the optical pulse train into a microwave signal. The microwave generator may also include a second servo amplifier that processes a low-frequency output of the microwave photodiode into a second servo signal that drives an optical modulator that modulates the optical pulse train. The microwave photodiode, optical modulator, and servo amplifier form a feedback loop that suppresses amplitude noise on the microwave signal. By reducing amplitude noise and relative intensity noise, phase noise caused by amplitude-to-phase noise conversion is minimized.
