<P><FONT SIZE=2>"According to David Hume causality is based on </FONT>
<BR><FONT SIZE=2>nothing more than the observed constant conjunction </FONT>
<BR><FONT SIZE=2>of two or more kinds of events, say A and B. </FONT>
<BR><FONT SIZE=2>It is a mere habit we have to call the earlier </FONT>
<BR><FONT SIZE=2>of the occurrences, say A, the cause, and the later, B, </FONT>
<BR><FONT SIZE=2>the effect; no relation of necessity, nor even of likelihood, </FONT>
<BR><FONT SIZE=2>of a B's succeeding an A in the future can be deduced.'</FONT>

<P><FONT SIZE=2>'We would like to think of teleportation as the transmission </FONT>
<BR><FONT SIZE=2>of quantum information from A to B. If we accept the intuitively </FONT>
<BR><FONT SIZE=2>appealing tenet that a transfer of information from sender </FONT>
<BR><FONT SIZE=2>to receiver must always be mediated by a channel connecting </FONT>
<BR><FONT SIZE=2>the two participants, teleportation appears paradoxical: </FONT>
<BR><FONT SIZE=2>If only two classical bits were sent, how did the full </FONT>
<BR><FONT SIZE=2>quantum information pass from A to B? Looking at the standard </FONT>
<BR><FONT SIZE=2>space-time diagram of the teleportation process, we see that </FONT>
<BR><FONT SIZE=2>there is indeed a second (V-shaped) path connecting A to B, </FONT>
<BR><FONT SIZE=2>which is defined by the two world lines of the distributed </FONT>
<BR><FONT SIZE=2>EPR particle pair. This leads to an intriguing interpretation </FONT>
<BR><FONT SIZE=2>(first proposed by Bennett soon after the discovery of teleportation): </FONT>
<BR><FONT SIZE=2>In addition to the two bits, the remaining quantum information </FONT>
<BR><FONT SIZE=2>must have been propagated backward in time from A to the EPR </FONT>
<BR><FONT SIZE=2>source and thence forward in time to B. Indeed, if we insist </FONT>
<BR><FONT SIZE=2>that information transmission requires a physical channel, </FONT>
<BR><FONT SIZE=2>there appears to be no other possible interpretation of </FONT>
<BR><FONT SIZE=2>the teleportation process! It is remarkable that this </FONT>
<BR><FONT SIZE=2>interpretation is entirely consistent: The principles </FONT>
<BR><FONT SIZE=2>of quantum measurement theory imply that the information </FONT>
<BR><FONT SIZE=2>sent backward in time is random and independent of </FONT>
<BR><FONT SIZE=2>the teleported state, so long as the two classical bits </FONT>
<BR><FONT SIZE=2>remain unknown. Hence, the well-known classical causal paradoxes </FONT>
<BR><FONT SIZE=2>of backward-in-time information propagation are neatly circumvented. </FONT>
<BR><FONT SIZE=2>This analysis, inspired by our informational point of view, </FONT>
<BR><FONT SIZE=2>also reveals a new significance for entanglement in quantum theory </FONT>
<BR><FONT SIZE=2>(beyond the traditional issues of nonlocal correlations </FONT>
<BR><FONT SIZE=2>of measurement outcomes): Entanglement can be viewed as providing </FONT>
<BR><FONT SIZE=2>a channel for the transmission of quantum information.'</FONT>
