If he means by distinguishing superposed electronic
states of a hydrogen atom (or molecule), that is a
_very_ tall order. Proximity effects from other atoms
will also disturb the system, limiting the volumetric
efficiency at the macroscopic scale.
Or is the state space of the entire system read/written to?
If so, thrre is a problem in determining the boundaries
of the system.
If the method involves degenerate states (i.e. neutronium)
of matter, then perhaps...
