Purdue University research news
Purdue University has created the Quantum Code Library, a complex collection of simulation engines to simulate next-generation nanoelectronics, under the direction of researcher Tillmann Kubis. With the help of this extensive code base, manufacturers may model semiconductors at the atomic level, focusing on devices as tiny as two or three nanometers. These tools provide a quick and inexpensive approach to forecasting how individual atoms impact transistor performance, in contrast to earlier techniques that needed enormous supercomputing power.
The library stands out due to its industry-driven development, which guarantees that the software tackles real-world issues that top IT firms encounter. These atomistic insights may now be incorporated into normal engineering processes with the help of customized software packages and licensing possibilities provided by the Purdue Innovates Office of Technology Commercialization.

The Single Atom Problem
The challenging “problem of a single atom” confronts the electronics industry as semiconductors continue to get smaller. Only around 16 atoms make up a silicon semiconductor at the 2-nanometer scale. Precision is now necessary for practical technology at this minuscule level, according to Kubis. “If the design has one more or fewer atom than the average, the entire system can change nonlinearly beyond 10%,” Kubis explained.
One major obstacle to mass production is this sensitivity. For the trillions of transistors that make up modern computer chips to work properly, each one must act in the same way. If even a small percentage of these transistors behave differently due to atomic differences, the entire device might not function. To ensure that these minuscule devices continue to function well and remain robust despite these atomic-scale challenges, the Quantum Code Library provides the precise modeling required.

Overcoming the Resource and Cost Issue
Atomistic simulations were formerly thought to be excessively costly and time-consuming. Researchers at Purdue University usually had to apply for and get project allocations on national supercomputers in the early 2010s since running such simulations may take millions of CPU hours. Atomic-scale variations from ideal device architectures could not be handled at that time with the reasonable statistics offered by several hundred samples.
The Purdue team has, however, created automated and systematic spectrum modifications that have radically altered the computing market. Without sacrificing prediction precision or atomic accuracy, these changes cut numerical costs by several orders of magnitude. As a result, researchers can now perform simulations that are significantly more complex than those from the preceding 10 years without relying on supercomputer allocations, using a very efficient simulation environment. Kubis emphasized this development, saying that because the library enables these activities to be finished swiftly on smaller computer clusters, he hasn’t had to apply for supercomputer resources in many years.

Industry-Driven Development
The Quantum Code Library stands out from other high-performing simulation tools created globally because of its strong match with industry objectives. Several Fortune 500 businesses and other industry leaders were directly involved in the building and funding of the Purdue library.
Kubis characterizes Purdue’s function as a “extended workbench” for these businesses. This close cooperation ensured that all of the material aspects, device design, and physical effects incorporated into the library provided nearly instantaneous answers to real-world industrial concerns. For the library to be at the forefront of commercial application, updates and new features frequently addressed particular industry concerns within a month of its release date.

Commercialization and the Rhino Framework
The Quantum Code Library’s intellectual property is safeguarded by registered copyrights and patents through the Purdue Innovates Office of Technology Commercialization (OTC). Several commercial simulation engines, most notably NEMO5, branded as Victory Atomistic by Silvaco Group Inc., are already powered by the library.
Purdue is improving the Rhino framework, which enables the complete customization of the library, to further improve the user experience. With Rhino, users may simplify large-scale programs into user-friendly tools designed for particular, unique circumstances. The development of “atomistic TCAD” is also made easier by this framework, which feeds atomistic data into conventional non-atomistic technology computer-aided design or TCAD tools. Density functional theory models and other material and physical chemistry tools are also being interfaced with the library, enabling the modeling of chemical processes involving millions of atoms.

Purdue’s Innovation Ecosystem Foundation
The Quantum Code Library is an essential aspect of Purdue Computes, an all-encompassing university program with four main pillars: semiconductor innovation, computer departments, physical AI, and quantum research. Support for this effort comes from the Purdue Innovates OTC, one of the most extensive technology transfer initiatives in the country. Purdue’s dedication to expanding knowledge at scale is demonstrated by the office’s report of 161 agreements completed and 269 innovations licensed in fiscal year 2025 alone.
Purdue institution, a top public research institution with over 106,000 students, sustains its “persistent pursuit of the next giant leap” with strategic projects such as the Mitch Daniels School of Business and its urban expansion into Indianapolis. The institution has maintained its commitment to affordability by freezing tuition on its main campus for 14 years in a row, even while it pushes the limits of technology.
Purdue provides nonexclusive rights for specific applications and possible software-as-a-service (SaaS) access to the Quantum Code Library for industry partners interested in licensing or commercializing the library.
