Postdoctoral Fellow (PREP0003891)

PREP Research Associate This 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. Quantum Transduction Postdoctoral Fellow The Quantum Nanophotonics group has recently demonstrated hybrid systems combining semiconductor optical quantum dots (QDs) and acoustic resonators as a promising platform for quantum information processing and transmission. All aspects of this work are performed 'in house' using NIST's state-of-the-art nanofabrication, molecular beam epitaxy, and low-temperature optical spectroscopy tools. The successful candidate will help lead this project, building on recent accomplishments, towards the goal of generating remote entanglement between superconducting qubits. U.S. Citizen Preferred Key Responsibilities Design and construct GHz frequency acoustic resonators in Gallium Arsenide. Precision spectroscopy of Indium Arsenide quantum dots (QDs) embedded in acoustical resonators. Epitaxial growth and nanofabrication of QD hybrid quantum systems. Analyze and interpret the 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 which 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.

Background Checks The successful candidate(s) for this position will be subject to a pre‑employment background check including education verification. EEO is the Law Vaccine Requirements Johns Hopkins University strongly encourages, but no longer requires, at least one dose of the COVID‑19 vaccine. The COVID‑19 vaccine does not apply to positions located in the State of Florida. We still require all faculty, staff, and students to receive the seasonal flu vaccine. Exceptions to the COVID and flu vaccine requirements may be provided to individuals for religious beliefs or medical reasons. Requests for an exception must be submitted to the JHU vaccination registry. This change does not apply to the School of Medicine (SOM). SOM hires must be fully vaccinated with an FDA COVID‑19 vaccination and provide proof of vaccination status. For additional information, applicants for SOM positions should visit and all other JHU applicants should visit The following additional vaccine requirements may apply, depending upon your campus. Please contact the hiring department for more information. The pre‑employment physical for positions in clinical areas, laboratories, working with research subjects, or involving community contact requires documentation of immune status against Rubella (German measles), Rubeola (Measles), Mumps, Varicella (chickenpox), Hepatitis B and documentation of having received the Tdap (Tetanus, diphtheria, pertussis) vaccination. This may include documentation of having two (2) MMR vaccines; two (2) Varicella vaccines; or antibody status to these diseases from laboratory testing. Blood tests for immunities to these diseases are ordinarily included in the pre‑employment physical exam except for those employees who provide results of blood tests or immunization documentation from their own health care providers. Any vaccinations required for these diseases will be given at no cost in our Occupational Health office. #J-18808-Ljbffr The American Ceramic Society
