This approach is based on the reduced density-matrix functional theory (RDMFT) formulation of the electronic structure problem. For that purpose, the density-matrix functional of the full system is decomposed into an indirectly coupled sum of density-matrix functionals for all its subsystems using the adaptive cluster approximation to RDMFT. The approximations involved in the decomposition and the adaptive cluster approximation itself can be systematically converged to the exact result. The solutions for the density-matrix functionals of the effective subsystems involves a constrained minimization over many-particle states that are approximated by parametrized trial states on the quantum computer similarly to the variational quantum eigensolver. The independence of the density-matrix functionals of the effective subsystems introduces a new level of parallelization and allows for the computational treatment of much larger molecules on a quantum computer with a given qubit count. In addition, for the proposed algorithm techniques are presented to reduce the qubit count, the number of quantum programs, as well as its depth. The evaluation of a density-matrix functional as the essential part of our approach is demonstrated for Hubbard-like systems on IBM quantum computers based on superconducting transmon qubits.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"https://journals.aps.org/prresearch/abstract/10.1103/PhysRevResearch.4.033160"}],"language":[{"iso":"eng"}],"doi":"10.1103/PhysRevResearch.4.033160","title":"Parallel quantum chemistry on noisy intermediate-scale quantum computers","year":"2022","author":[{"full_name":"Schade, Robert","first_name":"Robert","orcid":"0000-0002-6268-539","last_name":"Schade","id":"75963"},{"full_name":"Bauer, Carsten","last_name":"Bauer","first_name":"Carsten","id":"90082"},{"first_name":"Konstantin","last_name":"Tamoev","full_name":"Tamoev, Konstantin","id":"50177"},{"full_name":"Mazur, Lukas","last_name":"Mazur","first_name":"Lukas","orcid":" 0000-0001-6304-7082","id":"90492"},{"id":"16153","first_name":"Christian","last_name":"Plessl","orcid":"0000-0001-5728-9982","full_name":"Plessl, Christian"},{"id":"49079","first_name":"Thomas","last_name":"Kühne","full_name":"Kühne, Thomas"}],"publication_status":"published","date_updated":"2023-08-02T15:04:22Z","article_type":"original","intvolume":"         4"},{"date_updated":"2023-08-02T15:00:47Z","status":"public","year":"2022","title":"Roadmap on Electronic Structure Codes in the Exascale Era","author":[{"last_name":"Gavini","first_name":"Vikram","full_name":"Gavini, Vikram"},{"last_name":"Baroni","first_name":"Stefano","full_name":"Baroni, Stefano"},{"full_name":"Blum, Volker","last_name":"Blum","first_name":"Volker"},{"full_name":"Bowler, David R.","first_name":"David R.","last_name":"Bowler"},{"full_name":"Buccheri, Alexander","last_name":"Buccheri","first_name":"Alexander"},{"first_name":"James R.","last_name":"Chelikowsky","full_name":"Chelikowsky, James R."},{"full_name":"Das, Sambit","first_name":"Sambit","last_name":"Das"},{"first_name":"William","last_name":"Dawson","full_name":"Dawson, William"},{"full_name":"Delugas, Pietro","last_name":"Delugas","first_name":"Pietro"},{"first_name":"Mehmet","last_name":"Dogan","full_name":"Dogan, Mehmet"},{"last_name":"Draxl","first_name":"Claudia","full_name":"Draxl, Claudia"},{"first_name":"Giulia","last_name":"Galli","full_name":"Galli, Giulia"},{"last_name":"Genovese","first_name":"Luigi","full_name":"Genovese, Luigi"},{"last_name":"Giannozzi","first_name":"Paolo","full_name":"Giannozzi, Paolo"},{"full_name":"Giantomassi, Matteo","first_name":"Matteo","last_name":"Giantomassi"},{"last_name":"Gonze","first_name":"Xavier","full_name":"Gonze, Xavier"},{"last_name":"Govoni","first_name":"Marco","full_name":"Govoni, Marco"},{"first_name":"Andris","last_name":"Gulans","full_name":"Gulans, Andris"},{"full_name":"Gygi, François","first_name":"François","last_name":"Gygi"},{"full_name":"Herbert, John M.","last_name":"Herbert","first_name":"John M."},{"full_name":"Kokott, Sebastian","first_name":"Sebastian","last_name":"Kokott"},{"id":"49079","full_name":"Kühne, Thomas","last_name":"Kühne","first_name":"Thomas"},{"first_name":"Kai-Hsin","last_name":"Liou","full_name":"Liou, Kai-Hsin"},{"full_name":"Miyazaki, Tsuyoshi","first_name":"Tsuyoshi","last_name":"Miyazaki"},{"last_name":"Motamarri","first_name":"Phani","full_name":"Motamarri, Phani"},{"last_name":"Nakata","first_name":"Ayako","full_name":"Nakata, Ayako"},{"last_name":"Pask","first_name":"John E.","full_name":"Pask, John E."},{"id":"16153","full_name":"Plessl, Christian","first_name":"Christian","last_name":"Plessl","orcid":"0000-0001-5728-9982"},{"full_name":"Ratcliff, Laura E.","first_name":"Laura E.","last_name":"Ratcliff"},{"full_name":"Richard, Ryan M.","last_name":"Richard","first_name":"Ryan M."},{"first_name":"Mariana","last_name":"Rossi","full_name":"Rossi, Mariana"},{"id":"75963","last_name":"Schade","first_name":"Robert","orcid":"0000-0002-6268-539","full_name":"Schade, Robert"},{"first_name":"Matthias","last_name":"Scheffler","full_name":"Scheffler, Matthias"},{"full_name":"Schütt, Ole","first_name":"Ole","last_name":"Schütt"},{"first_name":"Phanish","last_name":"Suryanarayana","full_name":"Suryanarayana, Phanish"},{"last_name":"Torrent","first_name":"Marc","full_name":"Torrent, Marc"},{"full_name":"Truflandier, Lionel","first_name":"Lionel","last_name":"Truflandier"},{"full_name":"Windus, Theresa L.","first_name":"Theresa L.","last_name":"Windus"},{"last_name":"Xu","first_name":"Qimen","full_name":"Xu, Qimen"},{"first_name":"Victor W. -Z.","last_name":"Yu","full_name":"Yu, Victor W. -Z."},{"first_name":"Danny","last_name":"Perez","full_name":"Perez, Danny"}],"user_id":"75963","_id":"46275","language":[{"iso":"eng"}],"abstract":[{"text":"Electronic structure calculations have been instrumental in providing many\r\nimportant insights into a range of physical and chemical properties of various\r\nmolecular and solid-state systems.

We\nshow that these equations admit second-order modified equations which are\nHamiltonian and also possess first-order Lagrangians in modified coordinates.\nThe modified equation and its associated structures are computed explicitly\nfor the case of rotating travelling waves in the nonlinear wave equation.","creator":"coffen"}],"intvolume":"        14","article_type":"original","date_updated":"2023-08-10T08:44:55Z","publication_status":"published","author":[{"full_name":"McLachlan, Robert I","first_name":"Robert I","last_name":"McLachlan"},{"id":"85279","last_name":"Offen","first_name":"Christian","orcid":"https://orcid.org/0000-0002-5940-8057","full_name":"Offen, Christian"}],"title":"Backward error analysis for variational discretisations of partial  differential equations","year":"2022","doi":"10.3934/jgm.2022014","language":[{"iso":"eng"}]},{"department":[{"_id":"636"}],"type":"journal_article","date_created":"2021-08-11T08:24:02Z","file":[{"relation":"main_file","date_updated":"2021-12-13T14:56:15Z","file_name":"SymplecticShadowIntegration_AIP.pdf","access_level":"open_access","file_size":2285059,"file_id":"28734","content_type":"application/pdf","creator":"coffen","date_created":"2021-12-13T14:56:15Z"}],"related_material":{"link":[{"description":"GitHub","relation":"software","url":"https://github.com/Christian-Offen/symplectic-shadow-integration"}]},"abstract":[{"text":"Hamiltonian systems are differential equations which describe systems in classical mechanics, plasma physics, and sampling problems. They exhibit many structural properties, such as a lack of attractors and the presence of conservation laws. To predict Hamiltonian dynamics based on discrete trajectory observations, incorporation of prior knowledge about Hamiltonian structure greatly improves predictions. This is typically done by learning the system's Hamiltonian and then integrating the Hamiltonian vector field with a symplectic integrator. For this, however, Hamiltonian data needs to be approximated based on the trajectory observations. Moreover, the numerical integrator introduces an additional discretisation error. In this paper, we show that an inverse modified Hamiltonian structure adapted to the geometric integrator can be learned directly from observations. A separate approximation step for the Hamiltonian data avoided. The inverse modified data compensates for the discretisation error such that the discretisation error is eliminated. The technique is developed for Gaussian Processes.","lang":"eng"}],"publication":"Chaos: An Interdisciplinary Journal of Nonlinear Science","doi":"10.1063/5.0065913","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://aip.scitation.org/doi/abs/10.1063/5.0065913","open_access":"1"}],"article_type":"original","publication_status":"published","date_updated":"2023-08-10T08:48:14Z","author":[{"id":"85279","full_name":"Offen, Christian","orcid":"0000-0002-5940-8057","first_name":"Christian","last_name":"Offen"},{"full_name":"Ober-Blöbaum, Sina","first_name":"Sina","last_name":"Ober-Blöbaum","id":"16494"}],"title":"Symplectic integration of learned Hamiltonian systems","year":"2022","oa":"1","external_id":{"arxiv":["2108.02492"]},"quality_controlled":"1","citation":{"ieee":"C.
