Quantum System Analysis software, part of Keysight’s Quantum EDA platform, simulates quantum architectures at the system level. It unifies electromagnetic, circuit, and quantum dynamics domains to enable early design validation in a single environment.

By modeling the full quantum workflow—from initial design through system-level experiments—the software reduces reliance on costly cryogenic testing and shortens time-to-validation. It includes tools for optimizing dilution fridge input lines to manage thermal noise and estimate qubit temperatures. A time dynamics simulator models quantum system evolution using Hamiltonians derived from EM or circuit simulations, accurately emulating experiments such as Rabi and Ramsey pulsing to reveal qubit behavior.

Quantum System Analysis supports superconducting qubit platforms and can be extended to other modalities such as spin qubits. It complements Quantum Layout, QuantumPro EM, and Quantum Circuit Simulation tools.
