Electromagnetically Induced Transparency in Media with Rydberg Excitons 2: Cross-Kerr Modulation
Entropy, 2020 By mapping photons into the sample of cuprous oxide with Rydberg excitons, it is possible to obtain a significant optical phase shift due to third-order cross-Kerr nonlinearities realized under the conditions of electromagnetically induced transparency ...

Complete hyperentangled state analysis using weak cross-Kerr nonlinearity and auxiliary entanglement
New Journal of Physics, 2020 We present a new method for the complete analysis of hyperentangled Bell state and Greenberger–Horne–Zeilinger state in polarization and spatial-mode degrees of freedom, resorting to weak cross-Kerr nonlinearity and auxiliary frequency entanglement.

Quantum control gates with weak cross-Kerr nonlinearity [PDF]
Physical Review A, 2009 In this paper, with the weak cross-Kerr nonlinearity, we first present a special experimental scheme called C-path gate with which the realization of all possible bipartite POVMs of two-photon polarization states can be simpler and nearly deterministic.

Experimental demonstration of cavity-free optical isolators and optical circulators
Physical Review Research, 2020 Cavity-free optical nonreciprocity components, which have an inherent strong asymmetric interaction between the forward- and backward-propagation direction of the probe field, are key to produce such as optical isolators and circulators. According to the
