Fast Quantum State Reconstruction via Accelerated Non-Convex Programming

Fast Quantum State Reconstruction via Accelerated Non-Convex Programming

We propose a new quantum state reconstruction method that combines ideas from compressed sensing, non-convex optimization, and acceleration methods. The algorithm, called Momentum-Inspired Factored Gradient Descent (MiFGD), extends the applicability of quantum tomography for larger systems. Despite...
