Quantum Error Mitigation for Particle and Nuclear Physics (22-1b)

Organizers: Benjamin Nachman (LBNL), Christian Bauer (LBNL) , Wibe de Jong (LBNL), Kristan Temme (IBM), Abhinav Kandala (IBM) and Raphael Pooser (ORNL).

Error mitigation is critical for near term applications of nuclear and particle physics on quantum computers. The purpose of this workshop is to bring together a diverse cross-section of researchers from universities, national laboratories, and technology companies to address key challenges for achieving error reduction on near term devices. One important goal will be to identify important benchmark problems in particle and nuclear physics that can run on current hardware. Many problems in nuclear and particle physics have a resolution parameter (e.g. number of lattice sites) which can be dialed up to make solutions more precise and the corresponding quantum circuits naturally longer and more challenging to run. In order to compare different error mitigation approaches, it is essential to have common test cases of widespread importance.

Another aspect of this workshop will be to review existing approaches in initialization, gate, and readout error mitigation. In particular, we will study which approaches have been applied to particle and nuclear physics problems and which ones have not yet been applied, but may be useful. Furthermore, we will identify which tools may be adapted for further development particularly for nuclear and particle  physics problems including the incorporation of circuit structure [1], underlying symmetries [2], etc. Tools developed for and from [3] particle and nuclear physics may also have a wider applicability to other science and industrial applications of quantum computing. There is also an interplay between quantum computing errors and errors introduced from the approximations made in any calculation. Such errors are the result of field digitization [4], spacetime digitization, a finite spacetime volume, etc.[1] 2102.10008
