Query: Detecting entanglement of continuous variables with three mutually
  unbiased bases   An uncertainty relation is introduced for a symmetric arrangement of three
mutually unbiased bases in continuous variable phase space, and then used to
derive a bipartite entanglement criterion based on the variance of global
operators composed of these three phase space variables. We test this criterion
using spatial variables of photon pairs, and show that the entangled photons
are correlated in three pairs of bases.
