Oscillation-Free Unconventional Photon Blockade from Quadrature Driving of a Kerr Dimer
The episode discusses a paper demonstrating an unconventional photon blockade in a symmetric Kerr dimer using quadrature driving. The authors show how equal-amplitude fields with a ninety-degree phase difference enable oscillation-free antibunched light directly resolvable by standard detectors, even when the on-site Kerr nonlinearity is weak. The work suggests a method for achieving strong photon blockade without relying on large intrinsic nonlinearities.
