Impact of chaos on the excited-state quantum phase transition of the Kerr parametric oscillator
The Kerr parametric oscillator is a key platform for superconducting-qubit-based quantum technologies. This work helps pave the way for the development of more robust and reliable quantum devices by identifying the safe parameter landscape to avoid chaos and the breakdown of the excited-state quantum phase transition (ESQPT), which is a key feature for state stabilization.
