Same Ion Carries State and Motion - Ion-Trap Qubits: Sidebands, Shared Modes, and Fluorescence Readout Step by Step

The ion's internal bit and packet index share one source. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

The same ledger carries internal state and motion

The readout state is bright, pinned as bit 1, on the same checked trap source.

b_{\text{readout}}=1

The motion packet remains part of that source

The same source also carries packet index 2 and motional energy 4 joules.
