Transmon dispersive shift χ = g²·α/(Δ·(Δ + α)) (Koch 2007 finite-anharmonicity correction)

Layer 1 — Physicsin the superconducting-qubits subtree

Transmon dispersive shift with finite-anharmonicity correction (Koch et al. PRA 76, 042319, 2007). From framework F9 (transmon Hamiltonian diagonalisation), treating the transmon as a 3-level system (ground |g⟩, excited |e⟩, second-excited…
