Yes, radio waves are just lower frequency light waves, and light waves
are just higher frequency radio waves. And both have the properties of
photons as well as the properties of waves.

The important thing to realise is that photons don't have to be linked
to light, despite their name, because the light-related name was just a
historical accident of how they were discovered. The photons equivalent
to lower frequency electromagnetic radiation such as radio waves can't
be seen and get to and from antennae even if they are effectively
screened from the light.

Thanks for that polite response. I really could not ascertain an answer
through all the static before.

It appears my professor was mistaken, or perhaps he was telling us what
was known at that time.

Now what ham radio needs is a completely new type of communication. I am
thinking of those twin particles that react to one another regardless of
distance and without the delay of distance.

I think this was demonstrated very well on Star Trek. They can talk
across light years instantly. To bad Gene is dead. He could have helped
us all out with just how to do this. It was in all the scripts, it must
be true. It is my mythology so don't be making fun of it.

Read about quantum computers - way beyond my understanding - but instant
communication is probably not totally far-fetched. But anyone who
knows is welcom to contradict me on this!

You are talking about tangled quantum states. So far no one has figured
out how to use this to communicate over distances.

Scientists have figured out how to communicate quantum states over
several miles. It's a start, anyway.

It is known as Quantum entanglement communication. in theory it works
(and doesn't which is very quantum) it is similar to teleportation where
a particle has been teleported in as much as the defining state
information from the particle has been sent to another particle.
It is doubtful whether either can be brought into the macro world so it
could be a long time before anyone gets to say "beam me up Scotty".

The idea behind Quantum entanglement communication is that you create
quantum twin particles that are entangled and manipulate one to create
instant reaction with the other. "Spooky action at a distance"-Einstien.

And as soon as someone suggests it someone says it is not possible.
There is a No-Communication hypothesis that prevents the sending of
information via a quantum entangled state.

My head hurts now.

You're thinking of entangled particles?

One of the weird things about entanglement (and what Einstein called
"spooky action at a distance") is the following paradox:

- Measurements have shown that interacting with one of a pair of
entangled particles, has a definite effect on the state of the
other member of the pair. This effect occurs regardless of
distance, and isn't affected by lightspeed delay.

- You can't use this effect to send information faster than the speed
of light. At least, nobody has been able to, and (as I understand
it) there are good theoretical reasons to believe that it's just
not possible.

The reasons are (as I said, weird) that when you interact with
particle A, the effect on particle B is one which you can't actually
detect independently (that is, by measuring particle B alone). You
have to compare the measurement on Particle B, with information that
you can only get from the measurement that was taken Particle A, to
confirm that the effect actually occurred...

.... and in order to do this, you have to transmit that information
from the Particle A measurement site, to the particle B measurement
site, via some other means of communication... which occurs at the
speed of light (or slower).

I think this was demonstrated very well on Star Trek. They can talk

'Tis a fine mythology, and a great technology to hope for (and try to
discover).

Unfortunately, all of the tests which have been done on entangled
systems keep showing that entanglement is real, but (like
"superluminal" phase velocity) can't be used to send information
faster than C.

It's very frustrating.

With a million Particles A in a device called a 'transmitter'' and in a
distant galaxy, a million Particles B in a device called a 'receiver', a
statistical analysis would ensure to a high level of confidence that a
change had occurred. It wouldn't be difficult to arrange this to send
data. But this is mere technology, that exploits the properties inherent
in the entangled particles.

If the effect acts instantaneously over large distances, why can it not
be exploited?

It doesn't "must" exist. Measuring the state of either particle
determines the state of both. So how do you gain any information at the
receiving end by this? That's the problem. There is no way to transfer
info usefully.

What change exactly? How do you get *any* information from the million
particles?

What "effect" exactly? When the partner is observed, an entangled
particle resolves to a knowable state so that when you look at it, it is
in one state or the other. How do you know which state it will be in
until you observe it which causes the same thing, resolution to a
knowable state?

The possibility of a comms system must exist using this effect. That the
engineers haven't found a way to exploit it is a different issue.

One needs to lard in some other factor. Imagine Hertz asking what use
his waves could be, all he could do with them is turn them on and off.

The use of the words 'change' follows from a quote above, namely
"...Measurements have shown that interacting with one of a pair of
entangled particles, has a definite effect on the state of the other
member of the pair". So, something has changed, and it is measurable.
Perhaps the PP could expand on this.

A good question to ask here is: what is this change that takes place? It
is clearly measurable.

Unfortunately, all of the tests which have been done on entangled
systems keep showing that entanglement is real, but (like
"superluminal" phase velocity) can't be used to send information
faster than C.

If the effect acts instantaneously over large distances, why can it not
be exploited?

What "effect" exactly?

You'll need to ask that of the PP, as he used the word in his
explanation. I was thinking of a comms system that uses the effect
(whatever it is) to transfer information.

When the partner is observed, an entangled
particle resolves to a knowable state so that when you look at it, it is
in one state or the other. How do you know which state it will be in
until you observe it which causes the same thing, resolution to a
knowable state?

Perhaps it might help if we knew how many states were available.
