Physicists Build New Quantum Simulator to Control Individual Atoms
Eindhoven, Tuesday, 20 October 2026.
Researchers at Eindhoven University of Technology have created a custom quantum simulator, offering unprecedented control over atomic interactions to advance future quantum computing and drug discovery.
Bridging Quantum Mechanics and Practical Computing
In the field of deep-tech infrastructure, quantum computing represents a transformative leap forward from classical binary architecture [GPT]. At the Eindhoven University of Technology (TU/e) in the Netherlands, experimental physicist Rianne Lous, an assistant professor within the Coherence and Quantum Technology group at the Department of Applied Physics and Science Education, has constructed a custom quantum simulator [1]. Designed to observe and manipulate individual atomic interactions under strictly controlled conditions, this experimental platform moves quantum physics away from abstract theory into functional engineering [1].
How Neutral-Atom Manipulation Functions
The Sensing Interactions in Atomic Quantum Systems (SIntAQS) project operates as a closed vessel system engineered to measure subtle atomic behavior [1]. The hardware functions as a precise figurative knob, enabling researchers to tune distances between individual atoms and systematically adjust fundamental physical forces, including attraction, repulsion, energy exchange, and quantum entanglement [1]. This neutral-atom framework allows physicists to control quantum particles directively, establishing foundational control mechanics necessary for physical quantum processors [1].
Technical Challenges and Hardware Infrastructure
Development of the SIntAQS setup began in the summer of 2022 in the Qubit building at TU/e, though early operational progress faced logistical delays while outfitting the laboratory space [1]. The ongoing engineering work involves custom-fabricated components requiring extensive debugging and technical tuning, supported by a research team comprising eight students and two PhD candidates [1]. Parallel research within the broader neutral-atom quantum computing initiative at TU/e explores rubidium and strontium qubit architectures, incorporating microwave antenna arrays and optical control protocols designed for mid-circuit measurements and quantum error detection [2].
Targeted Applications from Cloud Computing to Medicine
The operational goals of the SIntAQS platform focus on expanding the infrastructure for advanced quantum computing and high-precision sensors [1]. Lous contributes directly to the large-scale Rydberg Atom Quantum Computing project led by Professor Servaas Kokkelmans, which seeks to connect neutral-atom quantum processors directly to Quantum Inspire, TNO’s public cloud platform [1]. Beyond raw computational power, a primary downstream application involves simulating protein interactions—complex biological molecules with intricate folding structures—to facilitate accelerated drug discovery and medical modeling [1].
