Keysight Expands Quantum Engineering Capabilities with Breakthrough System-Level Simulation Solution
Keysight Technologies, Inc. (NYSE: KEYS) today announced the release of Quantum System Analysis, an advanced Electronic Design Automation (EDA) solution that enables quantum engineers to model, simulate, and optimize quantum systems at the system level. This breakthrough marks a major milestone in Keysight’s commitment to accelerating quantum innovation and expands the company’s comprehensive Quantum EDA portfolio, which already includes Quantum Layout, QuantumPro EM, and Quantum Circuit Simulation.
The introduction of Quantum System Analysis comes at a defining moment for the field of quantum engineering. The 2025 Nobel Prize in Physics recently recognized pioneering work in superconducting quantum circuits—a core area directly aligned with Keysight’s latest innovation. As the global race toward scalable quantum computing intensifies, Keysight’s new tool provides the simulation accuracy and design efficiency needed to bridge research and real-world implementation.
Bridging the Gap in Quantum System Design
Designing reliable quantum systems has long posed a fundamental challenge due to the complex interplay between electromagnetic behavior, circuit dynamics, and quantum mechanics. Traditional workflows often rely on disjointed simulation tools and repeated cryogenic testing, which can stretch project timelines and inflate costs. These fragmented approaches limit engineers’ ability to analyze system-level performance early in the design process, resulting in extended iteration cycles and reduced efficiency.
Keysight’s Quantum System Analysis addresses these challenges head-on by integrating multiple physical domains into a single, cohesive simulation environment. By unifying electromagnetic, circuit, and quantum dynamics within one workflow, it enables engineers to perform system-level validation long before hardware testing begins. This integrated approach significantly reduces dependence on costly cryogenic experiments while improving overall design confidence and accelerating innovation cycles.
A Comprehensive Approach to Quantum Simulation
With Quantum System Analysis, researchers can now simulate the entire quantum workflow—from the initial circuit layout to full system-level experiments—within Keysight’s established EDA ecosystem. The platform enables engineers to model realistic experimental conditions, optimize system parameters, and predict performance outcomes before committing to physical builds.
A key advantage of the solution is its ability to replicate cryogenic environments virtually, allowing users to analyze the thermal and electromagnetic effects that influence qubit performance. By accurately simulating dilution fridge input lines, users can optimize system design to minimize thermal noise and ensure stable qubit operation at ultra-low temperatures. This approach not only saves time and resources but also helps improve qubit fidelity, coherence times, and overall system reliability.
Transformative New Features
Quantum System Analysis introduces two groundbreaking features that redefine the way engineers simulate and understand quantum systems:
- Time Dynamics Simulator
This feature models the time evolution of quantum systems using Hamiltonians derived directly from electromagnetic or circuit simulations. Engineers can perform detailed analyses of quantum experiments—such as Rabi and Ramsey pulsing—to visualize qubit behavior and interactions over time. By capturing the temporal dynamics of qubits, researchers gain deep insight into control sequences, decoherence mechanisms, and other factors that influence system performance. - Dilution Fridge Input Line Designer
This tool allows precise modeling of the cryostat input lines that connect room-temperature electronics to qubits. It enables engineers to analyze thermal noise propagation, estimate qubit temperatures, and design input line architectures that minimize thermal photon leakage. With this capability, teams can optimize their dilution fridge setups for maximum system fidelity—without extensive physical experimentation.
Together, these features represent a major leap forward in quantum system-level simulation, enabling predictive analysis that was previously only possible through iterative physical testing
Voices from Keysight
Chris Mueth, Senior Director for New Markets at Keysight, emphasized the significance of this release:
“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, highlighted the innovation’s strategic impact:
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.”
Accelerating Quantum Innovation
Quantum System Analysis extends Keysight’s Advanced Design System (ADS) 2026 platform, providing an integrated environment for quantum researchers and developers. It supports superconducting qubit architectures and can be adapted to other modalities, including spin qubits and emerging quantum technologies. This versatility makes it an essential tool for both academic researchers and industrial R&D teams pursuing next-generation quantum systems.
By combining system-level modeling with Keysight’s proven expertise in electronic and electromagnetic design, Quantum System Analysis helps engineers move from isolated device design to holistic system optimization. The result is a “shift-left” approach—bringing validation and optimization earlier in the design lifecycle, where it delivers the greatest impact.
