Impact of chaos on the excited-state quantum phase transition of the Kerr parametric oscillator
Ignacio García-Mata, Miguel A. Prado Reynoso, Rodrigo G. Cortiñas +4
The driven Kerr parametric oscillator, of interest to fundamental physics and quantum technologies, exhibits an excited state quantum phase transition (ESQPT) originating in an uns…
Driving superconducting qubits into chaos
Jorge Chávez-Carlos, Miguel A. Prado Reynoso, Ignacio García-Mata +4
Kerr parametric oscillators are potential building blocks for fault-tolerant quantum computers. They can stabilize Kerr-cat qubits, which offer advantages toward the encoding and m…
Effective versus Floquet theory for the Kerr parametric oscillator
Ignacio García-Mata, Rodrigo G. Cortiñas, Xu Xiao +4
Parametric gates and processes engineered from the perspective of the static effective Hamiltonian of a driven system are central to quantum technology. However, the perturbative e…
