Innsbruck, 15 September 2026. ParityQC, the Quantum Architecture Company, today launched the Parity Twine Optimizer, making its compiler(1) technology, which led to record-setting performance in executing the Quantum Fourier Transform, available as a product. Built on the ParityQC Architecture, it delivers uniquely efficient compilation and is now available via the IBM Qiskit Function, including a free trial upon request, giving developers and enterprises an easy way to put a clear technological head toward solving complex optimization problems. Applying QFT-record compilation to optimization on other paradigms. The Parity Twine Optimizer makes efficient compilation a reality: ParityQC’s Parity Twine Compilation has shown in published results that it delivers a significant reduction of gate count and depth in quantum optimization. It supports running larger and denser problems on real hardware today. It reduces the two-qubit gate overhead of compiling industry-relevant optimization problems, making larger and denser instances to be executed on today’s quantum hardware. The advantage is rooted in the structure of the Parity encoding itself rather than case-by-case tuning, so it holds across problem types and stays consistent as problems grow larger and more connected. The Parity Twine Optimizer is available now in the IBM Qiskit Functions Catalog, offered to IBM Quantum Network members through a 30-day free trial. It meets users where they already work: anyone in the IBM Quantum Network can bring record-efficient compilation into their own optimization problems and test it on IBM’s quantum hardware, without changing their setup or committing upfront. Its underlying compiler is hardware independent and available through ParityOS, ParityQC’s enabling software, and the technology will become accessible through further access routes in the future. “By offering the Parity Twine Optimizer as an IBM Qiskit Function, we are providing the quantum community with access to a tool with what we currently show to be the most efficient quantum compiler available for larger and more connected problems to run on real hardware,” said Magdalena Hauser and Wolfgang Lechner, co-CEOs of ParityQC. “Efficiency is paramount for useful results on today’s quantum computers. With ParityQC’s Parity Twine Optimizer now available in the IBM Qiskit Functions Catalog, our clients in the IBM Quantum Network have a new, powerful tool capable of scaling alongside the complex optimization problems they’re exploring,” said Scott Crowder, Vice President, IBM Quantum Adoption and Business Development. Key features of the Parity Twine Compilation include: Compile your circuits with maximum efficiency and minimal overhead in two-qubit gates. Eliminate the need for costly SWAP operations with the unique Parity Twine technology and leverage the full potential of quantum hardware today. Run larger problems on real hardware: Minimizes circuit depth and two-qubit gate overhead, so larger optimization problems run efficiently on today’s quantum processors. Higher performance, lower compilation overhead: Built on the state-of-the-art Parity Twine compilation, it reduces gate count and circuit depth while preserving algorithm quality, for faster execution and lower error accumulation. Adaptive and hardware independent: Supports arbitrary problem graph connectivity and adapts to your target hardware topology, including both heavy-hex (such as IBM Heron) and square-lattice (such as IBM Nighthawk) IBM Quantum QPUs, generating connectivity-aware circuits tuned to the problem graph density. Efficient end-to-end optimization: Solves full optimization workflows seamlessly with minimal, predictable QPU usage as you scale.

A new Qiskit function that integrates real-world constraints natively into the quantum computation, producing better and faster solutions to complex optimization problems, executed on IBM quantum hardware. MUNICH, Germany, September 15, 2026 — Aqarios GmbH today launched the Constrained Quantum Optimizer, a new solution in the IBM Qiskit Functions Catalog that organizations can use to help solve complex, real-world planning and scheduling problems using quantum computing. Built on Aqarios’ FlexQAOA algorithm, it integrates the constraints of an optimization problem natively into the quantum algorithm, producing better, valid solutions that penalty-based approaches can’t guarantee. Constrained Quantum Optimizer Behind many of an organization’s most consequential planning decisions lies an optimization problem: finding the best possible option from countless alternatives while satisfying a set of hard constraints. Businesses use it to cut costs, reduce travel time, allocate scarce resources, and improve efficiency. As these problems grow in size and complexity, classical methods become increasingly time consuming, making them ideal candidates for quantum approaches that can reach solutions beyond what classical methods can deliver today. Industries from logistics and manufacturing to telecommunications and energy solve problems like these every day. As organizations in these industries explore quantum computing, optimization functions like the Constrained Quantum Optimizer, in the IBM Qiskit Functions Catalog can be a starting point for putting it to work on real optimization problems. “Optimization is one of the most compelling categories of problems for the development of quantum advantage-capable applications. Now, through our Qiskit Functions Catalog, users can experiment with Aqarios’ Constrained Quantum Optimizer to push this boundary — and explore trusted results for constrained combinatorial optimization problems,” said Scott Crowder, Vice President, IBM Quantum Adoption and Business Development. Solving a constrained problem conventionally means folding its constraints into the objective function as penalty terms, a manual reformulation repeated for every new problem. This makes the problem harder to solve and no longer guarantees that the constraints are actually satisfied. Yet those constraints are always essential. The Constrained Quantum Optimizer works differently. It keeps a problem’s constraints intact and embeds them directly into the quantum circuit, ensuring that only valid solutions are ever considered. Take a delivery operation where every order must be loaded onto exactly one vehicle: never zero, never two. That kind of rule, called a one-hot constraint, is easy to state but just as easy for a solver to break. The Constrained Quantum Optimizer enforces it by design, so the computation never explores invalid solutions, uses the quantum hardware more effectively, and returns higher-quality results. Other kinds of constraints are handled automatically as well, with no extra work from the user. Businesses can describe their optimization problem in the standard formats their planning and operations teams already use, and the function takes care of everything else. To validate the approach on real hardware, Aqarios ran the function on an IBM Quantum Heron processor, on a 144-bit problem with 48 one-hot constraints. Across five test instances it reached optimal or near-optimal solutions every time, finding the exact optimum in three and landing within about one percent in the other two. “Most quantum optimization tools still make you work around your constraints. We build them in natively, and that’s what turns quantum computing into real, usable results for constrained problems,” said Michael Lachner, CEO, Aqarios. “We’re glad to bring what already runs on our Luna platform directly to IBM Quantum users, via the Qiskit Functions Catalog.” The Constrained Quantum Optimizer builds on FlexQAOA, which already powers constrained optimization for paying customers on Aqarios’ Luna platform. On that proven foundation, Aqarios combines the algorithm with approaches designed specifically for IBM quantum hardware, bringing it to the Qiskit Functions Catalog for developers, researchers, and businesses to use directly. The Constrained Quantum Optimizer is available now for IBM Quantum users through the IBM Qiskit Functions Catalog. About Aqarios Aqarios, headquartered in Munich, Germany, and a spin-off of LMU Munich, is a provider of quantum computing software for optimization across industries including energy, aerospace, logistics, finance, and manufacturing.
