Yea but information itself is not physical, it's organization of something physical.
you mean, this post?
You also mean, the structure of information? That's encoding, which is computation again.
Which is not information, it's what happens to it.
IT goes something like:
information is physical, commuting or transforming it takes energy.
You might adopt a river to carry you and a canoe downstream, by using the energy of the water and the way it modulates the canoe's position in time, thus carrying you somewhere. Or you might just want to send word (a message downstream "the natives are restless, send beads, and blankets"), so you write it down, put the message in a bottle which you seal with a stopper and turf into the tide. Maybe it would be more efficient to get a friendly native to paddle a canoe for you, etc.
You can't
reduce the information content of anything that has it, into less than 1s and 0s. Because you need more than one dimension.
We analyse the (information) entropy of signals in one dimension, by using at least one other dimension to see the one-dimensional signal in. You analyse a voltage or current in a$$\,\mathbb C^1 $$ dimension, and $$\mathbb 1_3 $$ time dimension, you analyse a spin phase in a $$\mathbb C^{2n} $$ dimension, and one $$\mathbb 1_z $$time dimension, both have discrete and continuous solutions, depending on the input-response parameter. See how time and complex phase space switch roles there? But both spaces have an entropy which can be measured.
P.S. The thing with the logical side of information and this thread, is that plenty of people can understand how to build logic circuits and not really need to understand how transistors work; there's a logical map of computing that avoids all that thermodynamics you need to know about with discrete devices when they don't behave like switches.
You can learn something about QM by looking at how to put together logical maps of the underlying dynamics - not thermodynamical as such, or "at minimum heat", so that the intrinsic spin dynamic isn't suppressed by a lot of noise. Even learning about how to do that or why it's done, why the preparation of circuits involves low temperatures or optics - the heat signal needs to be damped. There's a similar way in from the quantum logic angle (information is logical) that avoids quite a lot of theory.
