Quantum Imaging beyond the Diffraction Limit by Optical Centroid Measurements by Tsang, Mankei

“…I propose a quantum imaging method that can beat the Rayleigh-Abbe diffraction limit and achieve de Broglie resolution without requiring a multi-photon absorber or coincidence detection. Using the same non-classical states of light as those for quantum lithography, the proposed method requires only optical intensity measurements, followed by image post-processing, to produce the same complex quantum interference patterns as those in quantum lithography. …”

Bayesian Post-Processing Methods for Jitter Mitigation in Sampling by Weller, Daniel Stuart, Goyal, Vivek K.

“…Simulations demonstrate that this nonlinear algorithm can improve significantly upon the linear MMSE estimator, as well as the EM algorithm approximation to the maximum likelihood (ML) estimator used in classical estimation. Effective off-chip postprocessing to mitigate jitter enables greater jitter to be tolerated, potentially reducing on-chip ADC power consumption.…”

A general theoretical and experimental framework for nanoscale electromagnetism by Yang, Yi, Zhu, Di, Yan, Wei, Agarwal, Akshay, Zheng, Mengjie, Joannopoulos, John, Lalanne, Philippe, Christensen, Thomas, Berggren, Karl K, Soljacic, Marin

“…Even state-of-the-art nanoplasmonic studies2–4, exemplars of extremely interface-localized fields, rely on their validity. This classical description, however, neglects the intrinsic electronic length scales (of the order of ångström) associated with interfaces, leading to considerable discrepancies between classical predictions and experimental observations in systems with deeply nanoscale feature sizes, which are typically evident below about 10 to 20 nanometres5–10. …”
