Postdoctoral Fellow

Overview Johns Hopkins, founded in 1876, is America's first research university and home to nine world‑class academic divisions working together as one university. The position is part of the National Institute of Standards and Technology (NIST) Professional Research Experience Program (PREP). NIST recognizes that its research staff may want to collaborate with researchers at academic institutions on specific projects of mutual interest and, therefore, requires those institutions to be recipients of a PREP award. The PREP program involves staff from a wide range of backgrounds conducting scientific research across various fields. Individuals in this position will perform technical work supporting the collaboration's scientific research. Salary $6,745.50 - $6,995.33 Job Title PREP Research Associate – Quantum Transduction Postdoctoral Fellow Responsibilities Design and construct GHz frequency acoustic resonators in Gallium Arsenide. Precision spectroscopy of Indium Arsenide quantum dots (QDs) embedded in acoustic resonators. Epitaxial growth and nanofabrication of QD hybrid quantum systems. Analyze and interpret microwave and optical characteristics of the hybrid microwave/optical system. Work as a member of a collaborative, interdisciplinary team. Provide technical input to research problems that have been recognized as critical obstacles to progress in areas of exceptional interest. Prepare and review journal publications, contributing important advancements to quantum optics, quantum networking, optical communications, and optical measurement techniques. Attend research conferences and present technical results. Qualifications Doctoral degree in Physics or closely related field. Expertise in spectroscopy on optical two‑level systems at cryogenic temperatures, with specific emphasis on the resonance‑fluorescence method. Expertise in growth of compound semiconductors using Molecular Beam Epitaxy. Experience running and maintaining state‑of‑the‑art nanofabrication tools. Experience with optical measurement techniques such as coherent detection, confocal microscopy, laser diagnostics, noise characterization, and statistical optics. Experience in cryogenic measurements at liquid helium temperatures. Experience in finite‑element simulation of semiconductor electro‑mechanical devices. Strong oral and written communication skills. Ability to code with MATLAB or Python. Experience with maintaining and running a dilution refrigerator. Benefits Johns Hopkins offers a total rewards package that supports employees' health, life, career, and retirement.
