Superconducting Qubits 101: cQED Quantum Hardware
Part of the series Superconducting Qubits 101; cited as one entry below.
The first half builds a superconducting qubit from scratch: what a cloud-accessible qubit physically is, the ingredients of cQED, the classical and quantum LC oscillator, and how a Josephson junction's nonlinearity turns it into a transmon. The second half turns to design practice, walking through the chip design flow and Qiskit Metal: component libraries, parameter tuning, electromagnetic and quantum analysis with tools such as Ansys HFSS and EPR, and devices built with it.
- cQED ingredients: superconductivity, low temperature, Josephson nonlinearity, low dissipation
- Charge, flux, capacitance and inductance leading to the classical and quantum LC oscillator
- Transmon as an anharmonic oscillator, with ladder operators and wavefunctions
- Qiskit Metal workflow: layout, eigenmode/EPR and capacitive analysis, and example devices
Summary and key points drafted by a language model from the slides, not yet reviewed by me. The slides are the source.
