Dip Joti Paul

Dip Joti Paul is a graduate student in electrical engineering and computer science whose work aims to advance superconducting nanowire single-photon detectors for quantum sensing and mid-infrared imaging. His research addresses a long-standing challenge in the field: improving the accessibility of superconducting nanowire single-photon detectors by raising their operating temperature above 4 K, as observed in conventional devices. As a MathWorks Fellow, Dip Joti will explore high-critical-temperature superconducting materials, such as yttrium barium copper oxide, to develop detectors that could function above 77 K, potentially transforming applications from deep-space telescopes to portable quantum devices. Dip Joti relies on MATLAB’s Instrument Control Toolbox to automate high-throughput measurements in cryogenic environments, and the Curve Fitting Toolbox to analyze flux-flow resistivity in superconducting nanowires. He developed a custom MATLAB package, RefractEx, to calculate mid-infrared refractive indices of thin films from Fourier transform infrared spectroscopy measurements, which is now publicly available. His work could redefine performance standards for superconducting nanowire-based photon detectors, enabling more scalable, cost-effective technologies across quantum science, astronomy, and advanced spectroscopy.
