Multiphoton-state-assisted entanglement purification of material qubits
József Zsolt Bernád, Juan Mauricio Torres, Ludwig Kunz +1
We propose an entanglement purification scheme based on material qubits and ancillary coherent multiphoton states. We consider a typical QED scenario where material qubits implemen…
Partly invariant steady state of two interacting open quantum systems
József Zsolt Bernád, Juan Mauricio Torres
We investigate two interacting open quantum systems whose time evolutions are governed by Markovian master equations. We show a class of coupled systems whose interaction leaves in…
Unambiguous atomic Bell measurement assisted by multiphoton states
Juan Mauricio Torres, József Zsolt Bernád, Gernot Alber
We propose and theoretically investigate an unambiguous Bell measurement of atomic qubits assisted by multiphoton states. The atoms interact resonantly with the electromagnetic fie…
