A 1 bit signal cannot posses information. You'd require a minimum of 2 bits. 1 bit is just a straight line, no breaks.

You need at least two states, on and off. 1 and 0. Line and Gap. So a minimum of two bits.

Entanglement doersn't pass new information. It only passes information that's embedded into the system at the time of interaction, even if it's unknown.

It's like a quarter. You cannot tell if you will flip heads or tails. But the moment you do, you instantly know what you didn't flip.

Nothing new is created, no new information.

1 bit is information. 1 bit, by definition, has two states. For example, the presence or absence of a photon can convey the answer to yes/no questions.

1 bit is a single register of representation. You can have a million 0s, or a million 1s, but you cannot combine them in any way.

That's just a point, incapable of possessing information.

1-bit can never be information. Information is defined as the change of states. Not a state itself, and a 1-bit cannot change.

0000000000000000000000000

has no meaning.

111111111111111111111111111111111111

has no meaning.

00 = 0

01 = 1

That's information.

edit: Hey dumdums.... I get this is space and not philosophy of computation. But it's not a hard concept to grasp.

If you've got a single light switch. I can represent it as on or off. But by itself, it cannot represent information. On and Off is not information, it's data.

It's only a combination of ons and offs that qualify. And the moment you introduce something like iteration. Flipping the light switch on and off over time?

You introduce a new register. A new bit. It's no longer 1d data. Now it's 1d data over time. This is two dimensional. 1 bit of data, 1 bit of iteration. 2d. 2 bit, minimum for information passing.

A bit, by definition, is the possibility of a 0 or a 1.

Now, the problemHehe is you're sending a 0 or 1 with no context.

A bit, is a storage space for a representation. By the nature of dimensions, a single dimension, be it of physical space or data can never represent change. It's an isolated spot. In order to represent change (information) you have to have a second dimension. An x, and a y.

2-bits is the minimum state for information.

Information is not "defined as the change of states." That's simply not true.

Maybe that's what you understand it as, but it's not a standard scientific definition in any field.

Information theory? I don't know about you, but that's the one I'd go to if I were looking first.

That is not how it's defined in information theory.

That's the definition. Want me to show you where the change is a required part of it?

Change is not a requirement of that. Are you under the impression that "event" means "change"?

In order to derive you must alter the original data. It must change. That is the fundamental aspect of information.

It can change. If it cannot change, it's just data. Not information.
