The quantum effect of seperated particles also appears instantaneous regardless of distance, faster than light. Since up/down is binary this would provide information in the same way we code computers.

Am I correct?

You're describing entanglement which is a different phenomena than what I was referring to.

Entanglement is used in superdense coding (among other quantum computations) which works like this:

An intermediary entangles two quantum states and sends one to Alice and one to Bob. Alice can perform local operations to change the entangled state of the system. Since this changes the entanglement state (instantaneously, which is the heart of the EPR "paradox"), this "changes" Bob's result. Interestingly though, Bob needs to know the state of Alice's bit in order for his result to carry any *meaning* - and information about her bit can only be sent at the speed of light. So while the "state of entanglement information" seems to be transmitted faster than the speed of light to the other bit, Bob can't use just his bit to get information from Alice. His results only make sense in the context of her bit.

So, no, this isn't superluminal communication. Here, information is contained only in the pair of bits, not in either of the singletons.

But, Alice can send him her bit. The reason this is called superdense coding is because, in effect, two bits of information (one for Alice's bit, and one for Bob's bit) have been transmitted at the cost of only 1 transfer between Alice and Bob (plus the intermediary, but that's amortized). It's buy one get one free.
