With QuantumPro, Keysight Technologies introduces the EDA industry's first integrated electromagnetic (EM) design and simulation tool focused on the development of quantum computers based on superconducting qubits (quantum bit: two-state quantum system).
The QuantumPro solution combines the five essential functions of schematic design, layout creation, electromagnetic (EM) analysis, non-linear circuit simulation and quantum parameter extraction in the Advanced Design System (ADS) 2024 platform. Until now, the development of superconducting qubits usually required lengthy and expensive development cycles based on different tools.
QuantumPro combines the fields of quantum and microwave technology by translating conventional microwave results into easily adjustable quantum parameters within the ADS platform. QuantumPro enables developers to easily fine-tune their quantum circuits and significantly reduce the time-to-market of their chips and systems. Key features of the design and simulation solution include Keysight Technologies:
- Accelerated quantum chip development through cost-effective electromagnetic simulation approach based on MOM (Method of Moments). The non-linear circuit solver provides a comprehensive analysis of the power-dependent performance of quantum chips.
- Instead of solving the electric field in the entire volume, MOM only solves the currents on the metal surface, which significantly reduces computational costs. This enables the seamless tuning of qubits and resonators through co-simulation and parametric analysis.
- The non-linear circuit design environment (harmonic balance and X-parameters) simplifies the design of quantum amplifiers and critical blocks in the output chains of quantum systems, which improve readout fidelity. The Harmonic Balance Solver enables the design of amplifiers with few to thousands of Josephson junctions and provides a detailed analysis of amplifier performance, including gain profile, gain ripples, mixing products, quantum efficiency and gain compression.
- The Advanced Design System (ADS) contains a library of quantum layout components that include numerous commonly used quantum designs such as transmons and coplanar waveguide (CPW) meanderline resonators. This facilitates the creation of quantum chips within the ADS layout environment, with each geometric feature of the chip represented as a parameterized object that can be easily customized and optimized. The CPW components in the library have integrated air bridges, which play a crucial role in preventing the propagation of the CPW common mode.
