Keysight Technologies, Inc. (NYSE: KEYS) launches Quantum Circuits Simulation (Quantum Ckt Sim). It is a circuit design environment that speeds up the development of intricate quantum circuits. In partnership with Google Quantum AI, the new solution has advanced flux quantization, which is an industry-first achievement.
Google Quantum AI and Keysight’s partnership will enhance quantum circuit simulations through the integration of frequency-domain flux quantization into circuit solvers. By precisely modeling flux quantization, the new solution enables researchers to design more reliable and efficient superconducting circuits. The solution’s success sets a new standard for accuracy and efficiency of modeling superconducting circuits.
The new solution streamlines quantum workflow with advanced flux quantization in the frequency domain, providing unparalleled accuracy and capability in analyzing large, highly nonlinear quantum circuits. This enables researchers to model complex quantum circuits with better accuracy, reducing computational errors and enhancing the overall reliability of simulations.
The solution features a Quantum Devices Library that includes commonly used devices such as RF/DC SQUIDs, SNAILs, FLUXONIUMs, and SNAKEs within Keysight ADS. The solution offers a comprehensive design environment with nonlinear circuit simulators like harmonic balance, transient/convolution for time domain, circuit envelope for modulation domain, and an x-parameters nonlinear model generator. It also enhances quantum control by enabling the driving of superconducting circuits with external flux, providing precise manipulation of quantum circuits. Additionally, the tool simplifies the design of parametric quantum circuits, such as quantum amplifiers, which are essential for improving readout fidelity in quantum systems.
Ofer Naaman, Research Scientist, Google Quantum AI, said, “Using Quantum Ckt Sim, it is now possible to enforce flux quantization conditions in ADS frequency-domain simulations of superconducting devices. This is a critical capability whose absence thus far limited the usability of modern EDA tools in microwave superconducting circuit design.”
Mohamed Hassan, Quantum Solutions Planning Lead, Keysight EDA, said, “It’s thrilling to witness the accurate modeling of frequency domain flux quantization of superconducting circuits using an EDA tool for the first time. This significant milestone leverages EDA capabilities to streamline the design of superconducting microwave circuits for quantum applications and beyond. We anticipate this advancement will empower quantum engineers to enhance the performance of parametric quantum circuits, particularly in terms of power handling and bandwidth, which are crucial for the readout of qubits in quantum computers.”
