A03 “Building a Unified Platform for Finite Quantum Many-Body Computations”

A03 group is a group for computational science. We work on techincal aspects in the quantum matter science area
and build a uniform software platform. We need to combine various numerical methods, for example,
the Gaussian lobe method (A01 group), which provides precise results for up to 10 bodies, and the density functional theory (A02 group),
which is efficient for 40 or more bodies. Our group bridges these methods seamlessly and provides programs
to cover various computations. We will tune them for high-performance computing systems,
such as supercomputer Fugaku and GPU systems. Using quantum annealing will drastically reduce the computational cost
of finding the proper basis functions and parameters that cover the target quantum states.
We plan to provide a unified interface to these programs, which enables non-experts of theoretical computations to access
them easily.
