General Atomics (GA) is looking for a highly motivated post-doctoral quantum scientist to assist with GA’s growing interest in quantum computing (QC) for applications in energy sciences. The most immediate focus is the application of QC for chemistry and materials science research within the framework of magnetic fusion energy. The project(s) will be centered around formulations of quantum chemistry problems for QC hardware and simulators having significance towards first-wall and divertor surface chemistries. Specifically, the use of QC for investigating chemical reactions to elucidate various pathways and processes as it relates to interactions amongst surface-material and plasma species. To be successful in this role, the post-doctoral quantum scientist will need to be highly motivated and capable of independently formulating representations of the quantum chemical systems for quantum computation.
Duties and Responsibilities: • Construct target Hamiltonians of the system of interest and perform transformations to physical QC hardware. Systems include the electronic structure of atomic materials, scattering and many body interactions. • Implement quantum calculations on physical hardware and interpret results. • Perform electronic structure calculations on classical computers when necessary. • Work with scientists and engineers to investigate the fusion and fission relevant properties of novel material systems and propose new systems for investigation. • Disseminate work in peer-reviewed papers, conference presentations or patents where applicable.
Required Qualifications: • Ph.D. degree in Quantum Physics/Chemistry, Theoretical Chemistry, Chemical Physics, High Energy Physics or Mathematical Physics. • Must be able to formulate Hamiltonian for quantum chemical systems of interest, including first and second quantization representations, and map formulation to unitary quantum gate operations. This includes familiarity/knowledge of Jordan-Wigner and Bravyi-Kitaev transformations. • Strong foundation in electronic structure theory, e.g., Hartree-Fock (HF) and Post-HF methods including couple cluster theory and configuration interaction. • Knowledge of quantum information theory, QC hardware, quantum gate modeling, and/or quantum algorithm design. • Established history of conference presentations and peer-reviewed publications, preferably with emphasis on quantum chemistry problems using quantum computers.
Desired Additional Qualifications: • Familiar with quantum algorithm/gate programming using open libraries such as OpenFermion and/or QISKIT. • Experience using open source quantum chemistry codes such as NWChem, CP2K, and/or PSI4. • Familiar with quantum error-correction and fault-tolerant QC. • Familiar with quantum annealing and adiabatic QC approaches (e.g. QUBO). • Experience using QC hardware and simulators, including hardware based on semiconductor, photon, and/or ion trap platforms. • Knowledge of density functional theory and materials science. • Ability to learn and work independently in nascent field of QC. • Comfortable being part of a multidisciplinary team. • Ability to prioritize, coordinate tasks, and communicate concepts well with others.
