A driven quantum superconducting circuit with multiple tunable degeneracies
Jayameenakshi Venkatraman, Rodrigo G. Cortinas, Nicholas E. Frattini +2
We present the experimental discovery of multiple simultaneous degeneracies in the spectrum of a Kerr oscillator subjected to a squeezing drive. This squeezing, in combination with…
Spectral kissing and its dynamical consequences in the squeeze-driven Kerr oscillator
Jorge Chávez-Carlos, Talía L. M. Lezama, Rodrigo G. Cortiñas +5
Transmon qubits are the predominant element in circuit-based quantum information processing, such as existing quantum computers, due to their controllability and ease of engineerin…
On the static effective Lindbladian of the squeezed Kerr oscillator
Jayameenakshi Venkatraman, Xu Xiao, Rodrigo G. Cortiñas +1
We derive the static effective Lindbladian beyond the rotating wave approximation (RWA) for a driven nonlinear oscillator coupled to a bath of harmonic oscillators. The associated…
The squeezed Kerr oscillator: spectral kissing and phase-flip robustness
Nicholas E. Frattini, Rodrigo G. Cortiñas, Jayameenakshi Venkatraman +9
By applying a microwave drive to a specially designed Josephson circuit, we have realized an elementary quantum optics model, the squeezed Kerr oscillator. This model displays, as…
