英文摘要	We demonstrate an observation of zero to pi continuously controllable cross-phase-modulation based on an N-type electromagnetically-induced-transparency scheme in a room-temperature Rb-87 vapor. We theoretically and experimentally show that the signal field acquires a pi phase shift compared with the reference light in the presence of the phase-control field. Using the method of the optical Mach-Zehnder interferometer, we demonstrate that a zero to pi continuously controllable phase gate can be built by modulating the phase-control field. In addition, our theoretical calculation agrees well with the experimental observation, and the results presented in this work hold potential applications for the orthogonal polarization or vector gate in quantum information processing.
