I propose an effective theory of zero-temperature phases of the
quantum Hall stripes: a smectic phase where the stripes are
static and a novel quantum nematic phase where the positional
order is destroyed by quantum fluctuations. The nematic is viewed
as a Bose condensate of dislocations whose interactions are
mediated by a 
gauge field. Collective mode spectrum and
the dynamical structure factor in the two phases are calculated.
