Phase gate with a four-level inverted-Y system
- Department of Physics, University of Arkansas, Fayetteville, Arkansas 72701 (United States)
The four-level atomic system in an inverted-Y configuration is investigated for large Kerr nonlinearities. The cross-Kerr nonlinearity generated in such a system can produce a phase shift of order {pi} and can be used for realizing polarization quantum phase gates.
