    Quantum limits of localisation microscopy by Evangelia Bisketzi, Dominic Branford, Animesh Datta

    Published 2019-01-01
    “…We use the eigenvalues of the classical and quantum Fisher information matrices to compare the performance of spatial-mode demultiplexing and direct imaging in localisation microscopy with respect to the quantum limits.…”

    The best thermoelectrics revisited in the quantum limit by Sifan Ding, Xiaobin Chen, Yong Xu, Wenhui Duan

    Published 2023-10-01
    “…USA 93, 7436 (1996)], is revisited and discussed in the quantum limit. We express the thermoelectric figure of merit (z T) as a functional of electronic transmission probability $${{{\mathcal{T}}}}$$ T by the Landauer–Büttiker formalism, which is able to deal with thermoelectric transport ranging from ballistic to diffusive regimes. …”

    Beating Standard Quantum Limit with Weak Measurement by Geng Chen, Peng Yin, Wen-Hao Zhang, Gong-Chu Li, Chuan-Feng Li, Guang-Can Guo

    Published 2021-03-01
    “…As a further step, we introduce two modified weak measurement protocols to boost the precision beyond the standard quantum limit. Compared to previous works beating the standard quantum limit, these protocols are free of using entangled or squeezed states. …”

    Quantum limits to classically spoofing an electromagnetic signal by Jonathan N. Blakely, Shawn D. Pethel

    Published 2022-06-01
    “…Importantly, we show that the quantum limitations on classical spoofing remain significant even in the large mean-photon-number regime.…”

    On-chip coherent detection with quantum limited sensitivity by Vadim Kovalyuk, Simone Ferrari, Oliver Kahl, Alexander Semenov, Michael Shcherbatenko, Yury Lobanov, Roman Ozhegov, Alexander Korneev, Nataliya Kaurova, Boris Voronov, Wolfram Pernice, Gregory Gol’tsman

    Published 2017-07-01
    “…By optimizing the nanowire geometry and the working parameters of the detection scheme, we reach quantum-limited sensitivity. Our approach enables to realize matrix integrated heterodyne nanophotonic devices in the C-band wavelength range, for classical and quantum optics applications where single-photon counting as well as high spectral resolution are required simultaneously.…”

    Unveiling quantum-limited operation of interband cascade lasers by Simone Borri, Mario Siciliani de Cumis, Silvia Viciani, Francesco D’Amato, Paolo De Natale

    Published 2020-03-01
    “…A comprehensive experimental analysis of the frequency fluctuations of a mid-infrared interband cascade laser, down to the quantum-limited operation, is reported. These lasers differ from any other class of semiconductor lasers in their structure and internal carrier generation and transport processes. …”

    Laser manufacturing of spatial resolution approaching quantum limit by Xiao-Jie Wang, Hong-Hua Fang, Zhen-Ze Li, Dan Wang, Hong-Bo Sun

    Published 2024-01-01
    “…Herein, we report a spatial resolution improved to the quantum limit by exploiting a threshold tracing and lock-in method, whereby the two-order gap between atomic point defect complexes and optical diffraction limit is surpassed, and a feature size of <5 nm is realized. …”

    Magnetic Field-Resilient Quantum-Limited Parametric Amplifier by Mingrui Xu, Risheng Cheng, Yufeng Wu, Gangqiang Liu, Hong X. Tang

    Published 2023-02-01
    “…Superconducting parametric amplifiers are crucial components in microwave quantum circuits for enabling quantum-limited signal readout. The best-performing such amplifiers are often based on Josephson junctions, which however are sensitive to magnetic fields. …”
