Abstract: (649 Views)
In this paper, the generation of magnon-photon and magnon-superconducting qubit entanglement in an optical cavity and in the presence of Kerr medium have been investigated. By introducing the Hamiltonian and initial state of the system, time-dependent state ket, and also the steady-state ket of the system are achieved. Evaluating concurrence with different parameters shows that stronger coupling between the field and the superconducting qubit necessarily does not lead to a state with a higher amount of entanglement and also, sudden death and revival of the entanglement have been observed. With equal field-magnon and field-qubit couplings, the maximally entangled steady state is accessible.
