  3. PhaseLift But when (if ever) is the trace minimization problem equivalent to the rank minimization problem? A new methodology for phase retrieval Lift up the problem of recovering a vector from quadratic constraints into that of recovering a rank-one matrix from affine.
  4. Solving PhaseLift by low-rank Riemannian optimization methods for complex semide nite constraints ∗ Wen Huang y{K. A. Gallivan z Xiangxiong Zhang x May 24, Abstract A framework, PhaseLift, was recently proposed to solve the phase retrieval problem. In this frame-.

  6. Oct 16,  · PhaseLift is a recently introduced algorithm for phase recovery that is computationally tractable, numerically stable, and comes with rigorous performance guarantees. PhaseLift is optimal in the sense that the number of amplitude measurements required for phase reconstruction scales linearly with the dimension of the signal.
  7. Sep 01,  · The paper is organized as follows. In Section 2, PhaseLift and its connection with quantum state tomography are discussed. We are interested in applying the PhaseLift to adaptive quantum state tomography. In addition, a new scheme is proposed to distribute different number of copies of a state into different settings.
  8. 0 in Cnor Rn, the solution to PhaseLift is exact with probability at least 1 O(e m) if the number of equations obeys m c 0 n; () where c 0 is a su ciently large constant. Thus, exact recovery holds simultaneously over all input signals. In words, (1) the solution to most systems of quadratic equations can be obtained by semide nite pro-.
