Query: Multi-qubit quantum phase gates based on surface plasmons of a
  nanosphere   The Dicke subradiance and superradiance resulting from the interaction
between surface plasmons of a nanosphere and an ensemble of quantum emitters
have been investigated using a Green function approach. Based on such an
investigation, we propose a scheme for a deterministic multiqubit quantum phase
gate. As an example, twoqubit, threequbit, and fourqubit quantum phase gates
have been designed and analyzed in detail. Phenomena due to the losses in the
metal are discussed. Potential applications of these phenomena to
quantuminformation processing are anticipated.
