<p>Researchers reporting in the SPIE <em>Journal of Biomedical Optics</em> have developed a novel compact photoacoustic sensing instrument aimed at revolutionizing tissue diagnosis in biomedical sciences. This innovation addresses the need for cost-effective and rapid diagnostic tools by integrating multiple laser diodes within a compact casing and employing custom-built pulsed current supply units. Through experimental validation on human breast tissues, the instrument demonstrated remarkable capabilities in differentiating between normal and diseased tissues based on quanti...

<p><em>Photon-number resolution is crucial in various quantum systems, including quantum computation and communication. Superconducting nanostrip single-photon detectors (SNSPDs) are prominent in single-photon detection but face challenges in photon-number resolution fidelity and dynamic range. Researchers from the Shanghai Institute of Microsystem and Information Technology (SIMIT), Chinese Academy of Sciences, have made significant progress by widening superconducting strips. This innovation, detailed in Advanced Photonics, enables true-photon-number resolution up to 10 with the ...
