Steady-state spectral kissing and dissipative phase transitions
Devesh Karthik, Jorge Chávez-Carlos, Edson M. Signor +3
Spectral kissing, recently realized in a Kerr parametric oscillator (KPO), refers to the merging of pairs of energy levels and arises as a manifestation of an excited-state quantum…
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…
Quantum sensing in Kerr parametric oscillators
Jorge Chávez-Carlos, Daniela Garrido-Ramírez, A. J. Vega Carmona +5
Quantum metrology and quantum sensing aim to use quantum properties to enhance measurement precision beyond what could be classically achieved. Here, we demonstrate how the analysi…
Proposal for many-body quantum chaos detection
Adway Kumar Das, Cameron Cianci, Delmar G. A. Cabral +8
In this work, the term ``quantum chaos'' refers to spectral correlations similar to those found in the random matrix theory. Quantum chaos can be diagnosed through the analysis of…
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…
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…
