Abstract (in Japanese) (See Japanese page) 
(in English) The reduced density matrix in quantum many-body systems is extremely useful in elaborating physical properties, as it contains all the information of local physical quantities.
In particular, the reduced density matrix can be used for perturbation theory corrections and excitation state calculations, and is therefore considered to play an important role in the NISQ algorithm.
On the other hand, higher-order reduced density matrices above third order have been used in various quantum algorithms, such as ADAPT-VQE for dynamic circuit generation and qEOM for excitation energy determination, but the evaluation of higher-order reduced density matrices is not a scalable method due to the difficulties. This paper reports on the reduction of bottlenecks in the Quantum Subspace Expansion (QSE) method by reconstructing higher-order reduced density matrices from random sampling, without directly determining wave functions.
