Many-particle interference and entanglement controlled by undetected particles
ORAL
Abstract
Creating and manipulating entangled states are essential for performing various tasks in quantum information science. We present a unique interferometric scheme that allows us to generate many-particle entangled states. The unique feature of the scheme is that the entangled states can be manipulated without interacting with the entangled particles [1]. We illustrate the scheme by two special cases in which Bell states and GHZ-class states are produced. The scheme also emphasizes the connection between interference and entanglement, a connection that has been of interest in fundamental physics [2-4].
