Recently, we have shown theoretically [M.S. Shahriar, P. Pradhan, J. Morzinski, Phys. Rev. A 69 (2004) 032308] as well as experimentally [G. Cardoso, P. Pradhan, J. Morzinski, M.S. Shahriar, Phys. Rev. A 71 (2005) 063408] 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 wavelength locking of remote oscillators.
