Red Spacing Source Three-Row Scan - Ion-Trap Qubits: Sidebands, Shared Modes, and Fluorescence Readout Step by Step

Red sideband energy follows gap minus mode spacing. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

Red sideband energy falls as spacing grows

The gap stays eight joules and the starting packet stays two. The red drive subtracts one displayed mode spacing.

E_{\mathrm{red}}=8\ \text{J}\mathbin{-}1\ \text{J}=7\ \text{J}

Red sideband energy falls as spacing grows

The gap stays eight joules and the starting packet stays two. The red drive subtracts one displayed mode spacing.

E_{\mathrm{red}}=8\ \text{J}\mathbin{-}2\ \text{J}=6\ \text{J}

Red sideband energy falls as spacing grows

The gap stays eight joules and the starting packet stays two. The red drive subtracts one displayed mode spacing.

E_{\mathrm{red}}=8\ \text{J}\mathbin{-}3\ \text{J}=5\ \text{J}

The red drive is gap minus one spacing quantum

Each displayed spacing row gives its own red-drive energy. The packet update remains the same accepted one-step drop in all rows.
