Superconducting Qubits: LC Energy, Toy Josephson Coupling, and Readout Step by Step
A lightweight execution-visualization book.
LC Oscillators
LC Product Fixes Frequency Square
Larger L and C Slower the Mode
Same LC Source Binds the Mode Label
Charge and Flux Energy
Capacitor Energy Uses Charge and Capacitance
Inductor Energy Uses Flux and Inductance
Energy Transfer Keeps the Total
Toy Josephson Coupling
Current Times Flux Is an Energy Budget
Coupling Sign Changes the Energy Direction
Coupling Strength Is Not a Real Device Constant
Detuning, Readout, and Audit
Detuning Window Accepts a Nearby Mode
Far Detuned Mode Is Rejected
Readout Shift Crosses the Threshold
Superconducting Audit Cites Every Source
Relation Cross-Scans
LC Product Frequency-Square Cross-Scan
Toy Coupling Factor Cross-Scan
Detuning Boundary Cross-Scan
Readout Threshold Cross-Scan
Superconducting Source Audit Cross-Check
Source Calibration and Boundary Scans
Capacitance Source Frequency Three-Row Scan
Charge Energy Source Three-Row Scan
Flux Coupling Source Three-Row Scan
