PRESS RELEASE

WISER and Classiq Turn Quantum Theory into Working Reality

Washington, DC | May 12, 2026

The Washington Institute for STEM, Entrepreneurship and Research (WISER) announces the successful completion of a research collaboration with Classiq, on the Quantum Simulation of Coupled Harmonic Oscillators. The joint paper, published on arXiv, has been recognized by PennyLane as one of the Top 5 Quantum Algorithms Papers for Winter 2026 – described by PennyLane's editorial team Juan Miguel Arrazola, and Danial Motlagh as "a rare example of a serious practical analysis of an otherwise conceptual quantum algorithm, addressing challenges of initial state preparation and observable extraction."

From Equations to Executable Quantum Circuits

The research addresses one of the most persistent challenges in quantum computing; the wide gap between compelling theoretical algorithms and actual, deployable quantum circuits. The WISER and Classiq team investigated an algorithm originally proposed by Babbush et al. (Google Quantum AI) that promises exponential speedup over classical methods for simulating systems of coupled classical oscillators.

This algorithm can model a class of physical problems with deep relevance to materials science, structural engineering, molecular dynamics, and wave propagation modeling. Rather than treating the problem at the abstract level, the team grounded the algorithm in a concrete physical model; a linearly connected spring-mass system, and built a complete, end-to-end quantum circuit implementation using the Classiq quantum software platform.

"For a long time, quantum algorithms for physics were just beautiful theories on paper. Our work provides the first concrete, end-to-end quantum circuit designs for the Babbush et al. algorithm, explicitly detailing the construction of necessary oracles and block-encodings. While the algorithm requires fault-tolerant hardware, the specific resource costs are manageable and follow predictable scaling laws. This is very promising!" said Vardaan Sahgal, WISER

Technical Contributions That Move the Field Forward

This work provides a concrete implementation of the original quantum algorithm for simulating the evolution of classical coupled harmonic oscillators by explicitly constructing the algorithmic components required for state preparation and Hamiltonian evolution, including oracles whose existence is often assumed in theoretical treatments. For linearly coupled oscillators, three implementation strategies are investigated and benchmarked in terms of circuit-resource requirements. Within this connectivity structure, this work demonstrates that the initial state can be efficiently prepared compared to the originally prescribed routine, thereby reducing overhead while preserving the theoretical speedup guarantees of the algorithm.

“There is a large gap between the theoretical description of quantum algorithms, and implementing them efficiently in practice,” said Amir Naveh, CPO and co-founder of Classiq. “This joint work on the Coupled Harmonic Oscillators algorithm is a great example of how to build a practical implementation, considering many engineering and design challenges.” said Amir Navah, Co-founder & CPO at Classiq

Advancing Industry Impact

Critically, the work demonstrated two classes of physical applications with real-world reach, extraction of vibrational normal mode frequencies with potential quantum advantage over classical diagonalization of large matrices, and a coarse-grained energy transport framework for modeling wave propagation through physical media. These applications point toward future quantum solutions in domains ranging from molecular vibrational spectroscopy and advanced materials design to large-scale simulation of mechanical and acoustic systems.
