Engineering the quantum states of light in a Kerr-nonlinear resonator by two-photon driving

1 min read

AbstractPhotonic cat states stored in high-Q resonators show great promise for hardware efficient universal quantum computing.

Key Results

  • We propose an approach to efficiently prepare such cat states in a Kerr-nonlinear resonator by the use of a two-photon drive.
  • Significantly, we show that this preparation is robust against single-photon loss.
  • An outcome of this observation is that a two-photon drive can eliminate undesirable phase evolution induced by a Kerr nonlinearity.
