Here, we present a computationally-efficient method satisfying these criteria. The method partitions a quantum device into compact lumped or quasi-distributed cells. Each is first simulated individually. The composite system is then reduced and mapped to a set of simple subsystem building blocks and their pairwise interactions. The method operates within the quasi-lumped approximation and, with no further approximation, systematically accounts for constraints, couplings, parameter renormalizations, and non-perturbative loading effects.

One of the most daunting challenges is taming the numerous microscopic degrees of freedom ubiquitous in solid-state devices. State-of-the-art technologies, including the world's largest quantum processors, employ aluminum oxide (AlO\$\_x\$) tunnel Josephson junctions (JJs) as sources of nonlinearity, assuming an idealized pure \${\textbackslash}sin{\textbackslash}varphi\$ current-phase relation (C\${\textbackslash}varphi\$R). However, this celebrated \${\textbackslash}sin{\textbackslash}varphi\$ C\${\textbackslash}varphi\$R is only expected to occur in the limit of vanishingly low-transparency channels in the AlO\$\_x\$ barrier. Here we show that the standard C\${\textbackslash}varphi\$R fails to accurately describe the energy spectra of transmon artificial atoms across various samples and laboratories. Instead, a mesoscopic model of tunneling through an inhomogeneous AlO\$\_x\$ barrier predicts \%-level contributions from higher Josephson harmonics. By including these in the transmon Hamiltonian, we obtain orders of magnitude better agreement between the computed and measured energy spectra. The reality of Josephson harmonics transforms qubit design and prompts a reevaluation of models for quantum gates and readout, parametric amplification and mixing, Floquet qubits, protected Josephson qubits, etc. As an example, we show that engineered Josephson harmonics can reduce the charge dispersion and the associated errors in transmon qubits by an order of magnitude, while preserving anharmonicity.}, - archiveprefix = {arxiv}, - keywords = {Condensed Matter - Superconductivity,Quantum Physics}, - file = {C\:\\Users\\elevenso\\Zotero\\storage\\V9MDK5AW\\Willsch et al. - 2023 - Observation of Josephson Harmonics in Tunnel Junct.pdf;C\:\\Users\\elevenso\\Zotero\\storage\\RZ7YLQSA\\2302.html} -} -@article{aumannCircuitQOpensourceToolbox2022a, - title = {{{CircuitQ}}: An Open-Source Toolbox for Superconducting Circuits}, - shorttitle = {{{CircuitQ}}}, - author = {Aumann, Philipp and Menke, Tim and Oliver, William D. and Lechner, Wolfgang}, - year = {2022}, - month = sep, - journal = {New Journal of Physics}, - volume = {24}, - number = {9}, - pages = {093012}, - publisher = {{IOP Publishing}}, - issn = {1367-2630}, - doi = {10.1088/1367-2630/ac8cab}, - urldate = {2023-12-19}, - abstract = {We introduce CircuitQ, an open-source toolbox for the analysis of superconducting circuits implemented in Python.

The software implementation is capable of choosing the basis in a fully automated fashion based on the potential energy landscape. Additional features include the estimation of the T 1 lifetimes of the circuit states under various noise mechanisms. We review previously established circuit quantization methods and formulate them in a way that facilitates the software implementation. The toolbox is then showcased by applying it to practically relevant qubit circuits and comparing it to specialized circuit solvers. Our circuit quantization is applicable to circuit inputs from a large design space, and the software is open-sourced.

The challenge of designing a circuit is to compromise between realizing a set of performance metrics and reducing circuit complexity and noise sensitivity. At the same time, one needs to explore a large design space, and computational approaches often yield long simulation times. Here, we automate the circuit design task using SCILLA. The software SCILLA performs a parallelized, closed-loop optimization to design superconducting circuit diagrams that match predefined properties, such as spectral features and noise sensitivities. We employ it to design 4-local couplers for superconducting flux qubits and identify a circuit that outperforms an existing proposal with a similar circuit structure in terms of coupling strength and noise resilience for experimentally accessible parameters.
