We've focused on building a strong ecosystem of university, industry and government research in quantum computing. Our topics:

Quantum algorithms

A quantum algorithm is an algorithm able to be run on quantum computation platforms. A quantum software library is available, resulting from a host language added by quantum or classical systems. In comparison, classical systems refer to today's traditional computer, typically limited to a few particles by an exponential increase of required resources of digital computers (memory, computing time) which is considered to be less efficient than quantum simulations.

Quantum simulations

Classical simulations run on today’s traditional computer, typically limited to few Quantum simulations use quantum phenomena such as entanglement and tunneling to run algorithms meant to simulate the dynamics or the properties of quantum systems (e.g. molecules, materials..).

Dr. Hadfield’s research seeks to better understand the power of quantum computers. He studies quantum algorithms, information, and complexity, with applications to problems in physics, chemistry, and engineering, and seek computational problems and results elucidating where quantum computers have demonstrable advantages over classical algorithms. He is further interested in the mathematical foundations of quantum physics and computation. 

In particular, Dr. Hadfield is currently exploring the ability of quantum computers to provide practical and theoretical advantages for i) the simulation of physical systems and ii) approximately solving hard optimization problems.

Feynman Quantum Computing Academy at NASA Ames

An experience in the USRA-NASA-Google Quantum Artificial Intelligence (AI) Laboratory at NASA Ames Research Center’s Advanced Supercomputing Facility introduces graduate students to scientific opportunities in quantum information sciences and trains them to do research on the D-Wave 2XTM system. Students will receive valuable experience working on teams, undertaking projects in advanced computing, and developing quantum algorithms to solve problems in important application domains.

Students are accepted annually to the 12-week program. These students work in close collaboration with quantum scientists, receiving hands-on training, and undertake an individualized research project that involves application of quantum computing techniques to solve real world challenges in the domains of robotic exploration, air traffic management, and Earth and space science. Students will also participate in seminars and workshops with researchers from other organizations doing quantum research, including those from academic institutions, government laboratories, and commercial organizations. Students receive a stipend to cover living expenses and travel during the program.
