  Quantum nonlocality, i.e. the presence of strong correlations in spatially
seperated systems which are forbidden by local realism, lies at the heart of
quantum communications and quantum computing. Here, we use
polarization-entangled photon pairs to demonstrate a nonlocal control of
absorption of light in a plasmonic structure. Through the detection of one
photon with a polarization-sensitive device, we can almost deterministically
prevent or allow absorption of a second, remotely located photon. We
demonstrate this with pairs of photons, one of which is absorbed by coupling
into a plasmon of a thin metamaterial absorber in the path of a standing wave
of an interferometer. Thus, energy dissipation of specific polarization states
on a heat-sink is remotely controlled, promising opportunities for
probabilistic quantum gating and controlling plasmon-photon conversion and
entanglement.
