Bell-state generation for spin qubits via dissipative coupling
Ji Zou, Shu Zhang, Yaroslav Tserkovnyak
Abstract
Magnet-mediated dissipative coupling between spin qubits can be exploited to imprint long-lived quantum entanglement. This work points to a new direction for the application of spintronic schemes in future quantum information technologies, with an eye on the dynamical phase transitions associated with non-Hermitian dynamics of the reduced density matrix.
