Abstract
We present a new quantum cryptography implementation that uses frequency-correlated photon pairs to combine one-way operation with an autocompensating feature that has hitherto only been available in implementations that require the signal to make a round trip between the users. Furthermore, we describe a new scheme for creating frequency-correlated photon pairs (auto-phase-matched spontaneous parametric down-conversion). The new scheme offers several advantages over previous schemes, including the ability to generate frequency-correlated photon pairs regardless of the dispersion characteristics of the system.
