De onderzoekers stellen voor om een nieuwe methode te gaan ontwikkelen die ruizige kwantumcomputers simuleert op klassieke computers.

The researchers first propose to develop a novel method for simulating noisy quantum computers on classical computers. Next, they will use the new method for better predicting and reducing the influence of noise on the performance of near-term quantum computers.", "award_amount": 318864, "grant_id": "https://doi.org/10.61686/JPMXI72862", "summary_updates": [ { "submission_date": "2025-06-02T22:36:30", "update_en": "The proposed simulation method (on a regular computer) suffers from numerical rounding errors in practice (a known issue). Using mathematical proof, the researchers have first assumed that decimal numbers do not take up computer memory space (so that rounding errors do not occur) and confirmed that the proposed simulation method in principle can outperform existing approaches. This assumption does not hold for real computers, and fortunately the researchers have next also found a way to store these numbers using limited memory only.", "update_nl": "De voorgestelde simulatietechniek (door gewone computers) heeft in de praktijk last van afrondingsfouten (een bekend probleem). Door middel van een wiskundig bewijs hebben de onderzoekers eerst aangenomen dat decimale getallen geen computergeheugenruimte innemen (waardoor afrondingsfouten niet plaatsvinden), en bevestigd dat de methode sneller kan zijn dan bestaande simulatietechnieken. Die aanname geldt niet voor echte computers, en de onderzoekers hebben nu gelukkig ook een manier gevonden om deze getallen zó op te slaan, dat ze beperkte geheugenruimte nodig hebben." } ], "project_members": [ { "role": "Project leader", "member_id": 508947, "last_name": "Coopmans", "degree_pre_nominal": "dr.", "initials": "T.J.", "first_name": "Tim", "organisation": "Universiteit Leiden", "organisation_id": 38568, "ror": "https://ror.org/027bh9e22", "active": false }, { "role": "Researcher", "member_id": 508947, "last_name": "Coopmans", "degree_pre_nominal": "dr.", "initials": "T.J.", "first_name": "Tim", "organisation": "Universiteit Leiden||Faculteit der Wiskunde en Natuurwetenschappen||Leiden Institute of Advanced Computer Science (LIACS)", "organisation_id": 76843, "ror": "https://ror.org/027bh9e22", "active": false }, { "role": "Researcher", "member_id": 505497, "last_name": "Brand", "degree_post_nominal": "MSc", "initials": "S.O.", "first_name": "Sebastiaan", "organisation": "Universiteit Leiden||Faculteit der Wiskunde en Natuurwetenschappen||Leiden Institute of Advanced Computer Science (LIACS)||Data Science", "organisation_id": 491564, "ror": "https://ror.org/027bh9e22", "active": true }, { "role": "Project leader", "member_id": 508947, "last_name": "Coopmans", "degree_pre_nominal": "dr.", "initials": "T.J.", "first_name": "Tim", "organisation": "Technische Universiteit Delft||QuTech", "organisation_id": 75741, "ror": "https://ror.org/02e2c7k09", "active": true }, { "role": "Main Applicant", "member_id": 508947, "last_name": "Coopmans", "degree_pre_nominal": "dr.", "initials": "T.J.", "first_name": "Tim", "organisation": "Universiteit Leiden||Faculteit der Wiskunde en Natuurwetenschappen||Leiden Institute of Advanced Computer Science (LIACS)", "organisation_id": 76843, "ror": "https://ror.org/027bh9e22", "active": true } ], "products": [ { "title": "Advancing Quantum Computing with Formal Methods", "year": 2024, "edition": "1", "start": 420, "end": 446, "type": "Productbijdrage", "url_open_access": "https://doi.org/10.1007/978-3-031-71177-0_25", "journal_title": "Sprinter Nature", "authors": [ { "last_name": "Laarman", "initials": "A.", "role": "Auteur" }, { "last_name": "Quist", "initials": "A.", "role": "Auteur" }, { "last_name": "Mei", "initials": "J.", "role": "Auteur" }, { "last_name": "Coopmans", "initials": "T", "role": "Auteur" } ] }, { "title": "A Knowledge Compilation Map for Quantum Information", "year": 2026, "edition": "40", "start": 19406, "end": 19414, "type": "Wetenschappelijk artikel", "url_open_access": "https://doi.org/10.1609/aaai.v40i23.39018", "journal_title": "Proceedings of the AAAI Conference on Artificial Intelligence", "authors": [ { "last_name": "Laarman", "initials": "A.", "role": "Auteur" }, { "last_name": "Vinkhuijzen", "initials": "L.T.", "role": "Auteur" }, { "last_name": "Coopmans", "initials": "T.", "role": "Auteur" } ] } ] } ] }
