Keysight Unveils QuantumPro Workflow

Keysight Technologies, Inc. introduces QuantumPro, an electronic design automation (EDA) industry integrated electromagnetic (EM) design and simulation tool and workflow tailored for creation of quantum computers based on superconducting qubits. The QuantumPro solution consolidates five essential functionalities encompassing schematic design, layout creation, electromagnetic (EM) analysis, nonlinear circuit simulation and quantum parameter extraction into the Advanced Design System (ADS) 2024 platform.

Mainstream microwave engineers have been limited in their capability to address quantum design. Superconducting qubit development has typically required lengthy and expensive design cycles, along with the difficulty of navigating multiple point tools.

QuantumPro unites the domains of quantum and microwave engineering by intelligently translating traditional microwave outputs into easily adjustable quantum parameters within the ADS platform. QuantumPro empowers engineers to effortlessly fine-tune their quantum circuits and accelerate time-to-market for their chips and systems.

Key features of the QuantumPro design and simulation solution include:

• Accelerates development of quantum chips using an electromagnetic simulation approach based on the method of moments (MOM). The nonlinear circuit solver delivers extensive analysis of the power-dependent performance quantum chips.
• Instead of solving for the electric field in the full volume, MOM solves only for the currents on the metal surface. Enables tuning of qubits and resonators through co-simulation and parametric analysis.
• Simplifies design of quantum amplifiers, the critical blocks on the output chains of quantum systems that improve readout fidelity, using a nonlinear circuit design environment (harmonic balance and X-parameters). Harmonic balance solver handles amplifier design from just a few Josephson junctions up to thousands, delivering detailed analysis of the amplifier's performance, including gain profile, gain ripples, mixing products, quantum efficiency, and gain compression. 
• Incorporates a library of quantum layout components in ADS encompassing numerous frequently used quantum designs such as transmons and co-planar waveguide (CPW) meanderline resonators. Facilitates the creation of quantum chips from within the ADS layout environment with each geometrical feature of the chip being represented as a parameterized object that can be easily adjusted and optimized. 

“The tool provides high precision through its 3D EM simulators that span both finite element method (FEM) for frequency domain and eigenmode, and MOM for frequency domain analysis," Chris Mueth, senior director of Emerging Markets, Keysight EDA, says. "Automated quantum parameter extraction from frequency domain and eigenmode solutions allows easy optimization with built-in Python scripting. QuantumPro also elevates EM workflow for kinetic inductance modeling.”
