Description
Abstract:
Superconducting qubits currently rank high among the quantum hardware platforms that aspire to realize, ultimately, error-corrected quantum processors much larger than the ones available to date. A critical aspect, both historically as well as for the future roadmap of these devices, is the question of coherence times: for how long does a superconducting circuit faithfully represent quantum information stored in it, and what fidelities can we reach when performing gate operations on individual or pairs of qubits? This set of lectures will provide an introduction to the world of superconducting qubits from the perspective of modeling and simulation. Material to be covered includes the theoretical description of superconducting qubits like the transmon and fluxonium, the analysis of noise channels including 1/f charge and flux noise, and a hands-on tutorial to quantitative analysis of spectral properties and noise characteristics using the Python package "scqubits".
Participants are encouraged to install "scqubits" on their laptop prior to the lectures, see https://scqubits.readthedocs. for instructions.
