Lemniscate phase trajectories for high-fidelity GHZ state preparation in trapped-ion chains
Evgeny V. Anikin, Andrey Chuchalin, Dimitrii Donchenko +2
In trapped-ion chains, multipartite GHZ states can be prepared natively with the help of a single bichromatic laser pulse. However, higher-order terms in the expansion in the Lamb-…
Multi-photon Rabi oscillations in the presence of the classical noise in a quantum nonlinear oscillator
Bogdan Y. Nikitchuk, Evgeny V. Anikin, Natalya S. Maslova
We consider the model of a single-mode quantum nonlinear oscillator with the fourth (Kerr) and sixth (over-Kerr) orders of nonlinearity in the presence of fluctuations of the drivi…
Individual addressing of ion qubits with counter-propagating optical frequency combs
Evgeny Anikin, Lianna A. Akopyan, Mikhail Popov +3
We propose a new method of individual single-qubit addressing of linear trapped-ion chains utilizing two ultrastable femtosecond frequency combs. For that, we suggest implementing…
Ion native variational ansatz for quantum approximate optimization
Daniil Rabinovich, Soumik Adhikary, Ernesto Campos +6
Variational quantum algorithms involve training parameterized quantum circuits using a classical co-processor. An important variational algorithm, designed for combinatorial optimi…
The symmetry in the model of two coupled Kerr oscillators leads to simultaneous multi-photon transitions
Bogdan Y. Nikitchuk, Evgeny V. Anikin, Natalya S. Maslova +1
We consider the model of two coupled oscillators with Kerr nonlinearities in the rotating-wave approximation. We demonstrate that for a certain set of parameters of the model, the…
Multiphoton resonance in a driven Kerr oscillator in presence of high-order nonlinearities
Evgeny V. Anikin, Natalya S. Maslova, Nikolay A. Gippius +1
We considered the multiphoton resonance in the periodically driven quantum oscillator with Kerr nonlinearity in the presence of weak high-order nonlinearities. Multiphoton resonanc…
