WSE OHi!:¥ lightlike interval, and in particular is never separated by a timelike interval that can go backwards down the time stream, then timelike loops are avoided, along with the paradoxes they imply. Figure 11 shows such a system. Entangled photons in the two arms of the system are propagated through fiber-optic cables of equal length. Therefore, in the reference frame of the system, the send and receive events are simultaneous, and, aside from the latency associated with the reception of enough photons to establish the reception of a signal bit, the communication is instantaneous but does not create a timelike loop.

A Superluminal Nonlocal Communication System in Which the Communication Spans a Spacelike Interval XI. Example: Real-Time Earth Control of Mars Rover Now consider the application of a "rover" operated at interplanetary distances, with nonlocal communications used to provide rea l-time "virtual reality" control of the mobile device. Figure 12 shows a schematic of the Earth-based operation of a Mars rover. A base station on Mars would contain a high-intensity source of entangled photon pairs. One stream of photons from the entangled pairs, after passing through image slits, would be transmitted from the probe to an Earth control station, allowing a nonlocal signal to be "sent" from the control station by a time sequence of choices of whether to detect the stream of arriving photons as waves or particles . The other stream of photons from the entangled pairs, after passing through object slits, would be detected locally at the Mars base station near the source and analyzed for the presence or absence of an interference pattern, thereby "receiving" the nonlocal signal as a logical "0" or "1," respectively.
