Dipolar Coupling Errors in Nuclear Spin Qubits
Advanced Science, EarlyView.Multi‐nuclear spin registers of phosphorus‐atom qubits in silicon have demonstrated 99.99% single and >$>$99.9% two qubit gate fidelities. Despite nanometer separation, read‐out fidelities between individual nuclear spins within the register are not identical.

Chirp Signal Detection Performance Analysis Based on Generalized Stochastic Resonance
工程科学与技术, 2014 :For estimating the parameter information of target chirp signal within multiple chirp signal and noise,which is the conventional familiar model in signal processing,the stochastic resonance (SR) in over-damped bistable system driven by the multiple ...

Advanced Science, EarlyView.Niobium nitride (NbN) broadband plasmonic metasurface absorbers provide an efficient platform for solar‐energy conversion through hot‐carrier injection. Quasi‐epitaxial NbN features a low work function of 4.0 eV, reducing the interfacial injection barrier and facilitating charge transfer into adjacent photocatalysts.

Closing the Loop: High‐Precision 3D Photofabrication in Living Tissues
Advanced Science, EarlyView.Writing 3D microstructures inside living tissue demands more than laser access; It demands information. Hierarchical sensing captures thermal and mechanical states across pulse‐train, voxel, and structure timescales, feeding a controller that steers the laser in real time.

Allpass-Based Chirp Design With Perfect Pulse Compression Property
IEEE Open Journal of Signal ProcessingChirp waveforms are widely used in radar, sonar, acoustics, and other sensing systems due to their desirable pulse-compression behavior. However, standard chirp signals like linear frequency modulation (LFM) waveforms inevitably produce sidelobes that ...

Chirp Parameter Estimation Using Rank Reduction
, 1998 This paper considers the problem of estimating the bandwidth and the center frequency of a linear chirp signal from discrete-time noisy observations. The non-stationarity property of chirp signals implies that the signal has high rank and reduces the ...

Advanced Electronic Materials, EarlyView.The impact of Cu microstructure on the thermomechanical residual stress of TSVs with a diameter of 3 μm$\umu{\rm m}$ is investigated by comparing Raman stress imaging and EBSD grain characterization. By correlating Raman‐imaged TSV stress with Cu grain structure, direct experimental evidence is provided to highlight the direct correlation between ...

A method for the precise and absolute measurement of microwave chirp rates in cold-atom gravimeters
AIP AdvancesIn a cold-atom gravimeter based on Raman transition, the frequency of Raman lasers is controlled by microwave signals. The accuracy of the chirp rates of the microwave signals directly influences the accuracy of gravity measurements.
