Phys. Rev. Lett. 103, 150503 (2009) [4 pages]Giant Kerr Nonlinearities in Circuit Quantum ElectrodynamicsReceived 2 February 2009; published 8 October 2009 The very small size of optical nonlinearities places strict restrictions on the types of novel physics one can explore. This work describes how a single artificial multilevel Cooper pair box molecule, interacting with a superconducting microwave coplanar resonator, when suitably driven, can generate extremely large optical nonlinearities at microwave frequencies, with no associated absorption. We describe how the giant self-Kerr effect can be detected by measuring the second-order correlation function and quadrature squeezing spectrum. © 2009 The American Physical Society URL:
