Laser-free method for creation of two-mode squeezed state and beam-splitter transformation with trapped ions
Bogomila S. Nikolova, Peter A. Ivanov
We propose a laser-free method for creation of a phonon two-mode squeezed state and a beam-splitter transformation, using time-varying electric fields and non-linear couplings betw…
Quantum metrology with critical driven-dissipative collective spin system
Venelin P. Pavlov, Diego Porras, Peter A. Ivanov
We propose a critical dissipaive quantum metrology schemes for single parameter estimation which are based on a quantum probe consisting of coherently driven ensemble of spin-1…
Quantum chaos and thermalization in the two-mode Dicke model
Aleksandrina V. Kirkova, Peter A. Ivanov
We discuss the onset of quantum chaos and thermalization in the two-mode Dicke model, which describes the dipolar interaction between an ensemble of spins and two bosonic modes. Th…
Out-of-time-order correlator in the quantum Rabi model
Aleksandrina V. Kirkova, Diego Porras, Peter A. Ivanov
We investigate signatures of chaos and equilibration in the quantum Rabi model, which exhibits a quantum phase transition when the ratio of the atomic level-splitting to bosonic fr…
Quantum parameter estimation of nonlinear coupling in trilinear Hamiltonian with trapped ions
Peter A. Ivanov
I propose an efficient method for measuring non-linear coupling between the collective axial breathing mode and the radial rocking mode induced by the mutual Coulomb repulsion in l…
Enhanced Parameter Estimation with Periodically Driven Quantum Probe
Peter A. Ivanov
We propose a quantum metrology protocol for measuring frequencies and weak forces based on a periodic modulating quantum Jahn-Teller system composed of a single spin interacting wi…
