In the realm of superconducting quantum circuits, accurately
modeling flux quantization is paramount. This fundamental property
ensures that the magnetic flux through a superconducting loop is
quantized in discrete units, a critical aspect for the operation of
quantum circuits. Google Quantum AI and Keysight have collaborated
to address this challenge and 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 collaboration's success is detailed in a recently posted
technical paper, titled “Modeling flux-quantizing Josephson
junction circuits in Keysight ADS”. This paper demonstrates the
innovative approach to flux-quantization and its significant impact
on the field of quantum computing. The 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.
Key features of the Quantum Ckt Sim design and simulation
solution include:
- Quantum Devices Library – Incorporates a library of
quantum devices in Keysight ADS encompassing those most frequently
used such as RF/DC SQUIDs, SNAILs, FLUXONIUMs, and SNAKEs.
- Comprehensive Design Environment – Features a range of
nonlinear circuit simulators such as harmonic balance, transient /
convolution for time domain, circuit envelope for modulation
domain, and x-parameters nonlinear model generator.
- Enhanced Quantum Control – Enables the driving of
superconducting circuits with external flux, allowing for more
precise control and manipulation of quantum circuits in advanced
quantum computing applications.
- Streamlined design – Simplifies the design of parametric
quantum circuits including quantum amplifiers, the critical blocks
on the output chains of quantum systems that improve readout
fidelity.
Google Quantum AI, has established itself as a key player in the
quantum computing arena, driving significant advancements in the
field. With its state-of-the-art quantum processors and pioneering
research, Google has achieved notable milestones, including the
demonstration of beyond-classical computation and has been actively
involved in the development of advanced quantum amplifiers, which
are essential for enhancing the performance of 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.”
