Phys. Rev. Lett. 94, 050504 (2005) [4 pages]Detecting Vacuum Entanglement in a Linear Ion TrapReceived 8 August 2004; published 9 February 2005 We propose and study a method for detecting ground-state entanglement in a chain of trapped ions. We show that the entanglement between single ions or groups of ions can be swapped to the internal levels of two ions by sending laser pulses that couple the internal and motional degrees of freedom. This allows us to entangle two ions without actually performing gate operations. A proof of principle of the effect can be realized with two trapped ions and is feasible with current technology. © 2005 The American Physical Society URL:
