| dc.description | Current demonstrations of circuits with up to 10 physical qubits indicate that S–Qs are a preferred hardware platform for executing quantum computing1,2,3,4,5. Large-scale quantum information processing has become more possible with recent advancements in the times of qubit coherence6,7 and quantum fidelity of one- and two-qubit gates8,9 in superconducting circuits. S–Qs are controlled using ordinary microwave instruments and are created using regular nanofabrication and microfabrication techniques10,11. | |
| dc.description.abstract | In the present manuscript, we introduce a quantum system of two superconducting qubits (S–Qs) interacting with a quantized field under the influence of the Kerr nonlinear medium and Ising interaction. We formulate the Hamiltonian of the quantum model and determine the density operator of whole quantum system as well as quantum subsystems. We examine the dynamics of the quantumness measures for subsequent times including the S–Qs entanglement, S–Qs-field entanglement and quantum Fisher information in relation to the system parameters. Finally, we display the connection among the measures of quantumness during the time evolution.
