Physicists develop efficient modem for a future quantum internet

I’ve thought this up before and figured someone was already working on it.

Note: I will not use the term qubits, because the 4 possible states of a qubit are irrelevant in the context of network communication. There are two possible states, tangled and untangled(which is a traditional stable 0 or 1). Tangled and untangled are the new and instantaneous 0 or 1.

After standard handshake to establish a connection, both sides of the connection send entangled bits. One side of the tangle is sent over the wire, the other side is stored locally. At their leisure, the receiver of the connection disentagles or leaves tangled the bits to indicate 1 or 0. The other side, who originally sent the tangled bits, who sees the locally stored half of the tangle become untangled.

A preamble of solid disentangles would indicate that information is being sent, followed by a fixed number of entagled bits that will indicate the length of the message. The receiver watches for a postamble at the sequence immediately after the message. When the postamble is disentangled, the receiver knows to contents of the packet transmission (selective disentaglement) is complete.

The time to establish the initial connection remains is the same as it always was, and rate at which the information is sent is going to be a balancing act, but once the entangled bits are at each end, the transmission of information is dependent only on how fast the machine can resolve the selected entangled bits to a stable state, rather than how long at takes for the information to travel across the net.

At least thats how I’d do it.
