Carrier and Sidebands

Red Sideband Removes One Packet

The red sideband spends one motional packet. 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 sideband cites the trap gap and packet spacing

The trap source has gap 8 joules and spacing 2 joules.

Red sideband subtracts one motional packet from the gap

The drive energy is 6 joules, taking packet 2 to packet 1.
