  Recently, we have shown how the phase of an electromagnetic field can be
determined by measuring the population of either of the two states of a
two-level atomic system excited by this field, via the so-called Bloch-Siegert
oscillation resulting from the interference between the co- and
counter-rotating excitations. Here, we show how a degenerate entanglement,
created without transmitting any timing signal, can be used to teleport this
phase information. This phase-teleportation process may be applied to achieve
absolute phase-mapping of remote clocks.
