Center node: "phase retrieval without small ball probability assumptions"
  Abstract: In the context of the phase retrieval problem, it is known that certain natural classes of measurements, such as Fourier measurements and random Bernoulli measurements, do not lead to the unique reconstruction of all possible signals, even in combination with certain practically feasible random masks. To avoid this difficulty, the analysis is often restricted to measurement ensembles (or masks) that satisfy a small-ball probability condition, in order to ensure that the reconstruction is unique. This paper shows a complementary result: for random Bernoulli measurements, there is still a large class of signals that  can  be reconstructed uniquely, namely, those signals that are  non-peaky . In fact, this result is much more general: it holds for random measurements sampled from  any  subgaussian distribution    $ \mathcal {D}$   , without any small-ball conditions. This is demonstrated in two ways: 1) a proof of  stability and uniqueness  and 2) a uniform recovery guarantee for the  PhaseLift algorithm . In all of these cases, the number of measurements    $m$    approaches the information-theoretic lower bound. Finally, for random Bernoulli measurements with erasures, it is shown that PhaseLift achieves uniform recovery of all signals (including peaky ones).
