Tavis-Cummings model and collective multiqubit entanglement in trapped ions
Alex Retzker, E. Solano, Benni Reznik · Physical Review A · 2007
We present a method of generating collective multiqubit entanglement via global addressing of an ion chain performing blue and red Tavis-Cummings interactions, where several qubits are coupled to a collective motional mode. We show that a wide family of Dicke states and irradiant states can be generated by single global laser pulses, unitarily or helped with suitable postselection techniques.
