Keysight Technologies Launches Quantum System Analysis: A Significant Leap in Quantum Engineering

The announcement of Quantum System Analysis comes on the heels of the 2025 Nobel Prize in Physics, which recognized remarkable advances in superconducting quantum circuits—a crucial area that Keysight’s new solution is set to enhance. As the quantum landscape continues to evolve, this new capability represents a significant expansion of Keysight’s existing Quantum EDA portfolio, which includes Quantum Layout, QuantumPro EM, and Quantum Circuit Simulation.

Historically, system-level quantum analysis has been hindered by the intricate task of integrating diverse physical domains—such as electromagnetic, circuit, and quantum dynamics—into a cohesive simulation environment. Traditional methodologies often depend on fragmented tools and costly cryogenic experiments that can prolong development cycles and increase expenses.

Keysight’s Quantum System Analysis offers a solution to these challenges by providing a unified platform that streamlines the validation of quantum system designs. By reducing reliance on traditional cryogenic testing, the new tool enhances both development efficiency and design confidence.

Quantum System Analysis introduces two transformative features that are set to revolutionize the way researchers approach quantum experiments:

This feature allows users to model the time evolution of quantum systems using Hamiltonians derived from electromagnetic or circuit simulations. It facilitates accurate simulations of quantum experiments, including Rabi and Ramsey pulsing, enabling researchers to gain deeper insights into qubit behavior over time.

This tool enables precise modeling of cryostat input lines to qubits, essential for conducting thermal noise analysis and effective qubit temperature estimation. By simulating the fridge’s input architecture, engineers can minimize thermal photon leakage, thus improving overall system fidelity.

Chris Mueth, Senior Director for New Markets at Keysight, emphasized the importance of this launch: “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.”

Similarly, Mohamed Hassan, Quantum Solutions Planning Lead at Keysight, highlighted the impact of the new solution: “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 integrated within Keysight’s Advanced Design System (ADS) 2026 platform and complements existing quantum EDA solutions. The tool is tailored to support superconducting qubit platforms while remaining extensible to other modalities, such as spin qubits, making it a versatile asset for quantum research and development teams.

Keysight Technologies’ Quantum System Analysis heralds a new era in quantum engineering, providing researchers with advanced tools to streamline the design and validation of quantum systems. As the field continues to grow, this innovative solution positions Keysight at the forefront of quantum technology, facilitating faster and more efficient development cycles for the next generation of quantum innovations.
