Beyond Classical Boundaries
Why Quantum Simulation Matters for Engineering
Quantum computing pushes design beyond classical limits, demanding precision across electromagnetic, photonic, and superconducting domains. Building reliable quantum hardware means solving challenges like EM interference, optical losses, and parasitic coupling—issues that can derail performance at scale. Ansys delivers the simulation depth engineers need, from HFSS for electromagnetic design to Lumerical for photonic circuits and RaptorQu for superconducting QPU layouts, enabling faster innovation and fewer costly iterations.
The Quantum Hardware Challenge
- Electromagnetic Noise
Tiny electromagnetic disturbances can collapse quantum states. Ansys HFSS models 3D electromagnetic fields to minimize interference and optimize component performance for quantum systems. - Photonic Circuit Complexity
Quantum photonics require precise light-matter control. Ansys Lumerical enables full-stack photonic simulation — from waveguides to detectors.
- Parasitic Coupling in Packaging
Crosstalk and parasitics degrade signal fidelity. With RaptorQu, you can simulate quantum packaging at atomic resolution to eliminate hidden risks. - Cryogenic Thermal Instability
Quantum devices operate near absolute zero, where even minor thermal fluctuations can disrupt qubit coherence. Ansys multiphysics tools model thermal behavior in cryogenic environments, ensuring stability for superconducting and photonic systems.
Design and validate quantum chip layouts and interconnects.
