Keysight Technologies has announced the launch of Quantum System Analysis, a groundbreaking Electronic Design Automation (EDA) solution designed to help quantum engineers simulate and optimize quantum systems at the system level. This innovation represents a major expansion of Keysight’s Quantum EDA portfolio, which already includes Quantum Layout, QuantumPro EM, and Quantum Circuit Simulation. The release arrives at a defining moment for the quantum industry just after the 2025 Nobel Prize in Physics honored breakthroughs in superconducting quantum circuits, a key area directly aligned with Keysight’s latest solution.
System-level quantum analysis has long posed a significant challenge due to the difficulty of integrating multiple physical domains electromagnetic, circuit, and quantum dynamics within a single simulation environment. Traditional methods often depend on disconnected tools and repetitive cryogenic experiments, leading to extended development times and high costs. Keysight’s Quantum System Analysis addresses this challenge by offering a unified platform that enables early system-level validation, shortening development cycles and boosting design confidence.
With this solution, researchers can simulate the entire quantum workflow from early design through to system-level experimentation minimizing dependence on expensive cryogenic testing and accelerating time-to-validation. The platform’s integrated capabilities also allow users to simulate quantum experiments while optimizing dilution fridge input lines for thermal noise control and qubit temperature estimation, enabling more efficient and accurate quantum design.
Transformative Capabilities in Quantum System Design
Quantum System Analysis introduces two breakthrough features that redefine how engineers simulate and optimize quantum systems:
Time Dynamics Simulator: This feature models the time evolution of quantum systems using Hamiltonians derived from electromagnetic or circuit simulations. It enables precise simulation of experiments such as Rabi and Ramsey pulsing, giving researchers deeper insight into qubit behavior over time and improving experimental accuracy.
Dilution Fridge Input Line Designer: This tool allows detailed modeling of cryostat input lines connected to qubits, supporting thermal noise analysis and accurate qubit temperature estimation. By simulating the fridge’s input architecture, engineers can reduce thermal photon leakage and significantly enhance system fidelity.
Chris Mueth, Senior Director for New Markets at Keysight, said:
“Quantum System Analysis marks the completion of a truly unified quantum design workflow, seamlessly connecting electromagnetic and circuit-level modeling with comprehensive system-level simulation. By bridging these domains, it eliminates the need for fragmented toolchains and repeated cryogenic testing, enabling faster innovation and greater confidence in quantum system development.”
Mohamed Hassan, Quantum Solutions Planning Lead at Keysight, added:
“Quantum System Analysis is a leap forward in accelerating quantum innovation. By shifting left with simulation, we reduce the need for repeated cryogenic experiments and empower researchers to validate system-level designs earlier in the development cycle.
Quantum System Analysis is now available as part of Keysight’s Advanced Design System (ADS) 2026 platform, complementing the company’s existing suite of quantum EDA solutions. It currently supports superconducting qubit platforms and can be extended to other modalities such as spin qubits, making it a versatile and forward-looking tool for quantum R&D teams.
