Symmetries of the squeeze-driven Kerr oscillator
Francesco Iachello, Rodrigo G. Cortiñas, Francisco Pérez-Bernal +1
We study the symmetries of the static effective Hamiltonian of a driven superconducting nonlinear oscillator, the so-called squeeze-driven Kerr Hamiltonian, and discover a remarkab…
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…
Mapping Molecular Hamiltonians into Hamiltonians of Modular cQED Processors
Ningyi Lyu, Alessandro Miano, Ioannis Tsioutsios +7
We introduce a general method based on the operators of the Dyson-Masleev transformation to map the Hamiltonian of an arbitrary model system into the Hamiltonian of a circuit Quant…
Quantum tunneling and level crossings in the squeeze-driven Kerr oscillator
Miguel A. Prado Reynoso, D. J. Nader, Jorge Chávez-Carlos +6
The quasi-energy spectrum recently measured in experiments with a squeeze-driven superconducting Kerr oscillator showed good agreement with the energy spectrum of its corresponding…
A diagrammatic method to compute the effective Hamiltonian of driven nonlinear oscillators
Xu Xiao, Jayameenakshi Venkatraman, Rodrigo G. Cortiñas +2
In this work, we present a new diagrammatic method for computing the effective Hamiltonian of driven nonlinear oscillators. At the heart of our method is a self-consistent perturba…
