Postdoctoral Fellow (PREP0003891) Full-time

Postdoctoral Fellow

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.

Research Title: Quantum Transduction Postdoctoral Fellow

The work will entail: 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
