But not being material things with mass they can't in theory carry charge. [?] OK, its an absence of at least some the ubiquitous base existence so shouldn't.
Yet electron holes in a wire are said to be positively charged compared to the electrons. They too aren't material entities with mass but an absence.
Ejected 'bubble' electron holes do provide a [difference] that we can not call a charge in this context, but maybe can call it so in other contexts] source for the sustained traveling magnetic and electric fields. A Bit-photon body that possesses the fields that are expresses perpendicular to the Bit direction of travel.
The separable Bob wave, obtained by sympathetic vibration with parent atom, has to be different to the Bit motion dependent field waves.
