Intuitively, if a density operator has small rank, then it should be easier to estimate from
experimental data, since in this case only a few eigenvectors need to be learned. We prove …

Quantum state tomography (QST) refers to any method that allows one to reconstruct the
accurate representation of a quantum system based on data obtainable from an experiment …

We present a novel method for performing quantum state tomography for many-particle
systems, which are particularly suitable for estimating the states in lattice systems such as of …

We introduce a method for extracting meaningful entanglement measures of tensor network
states in general dimensions. Current methods require the explicit reconstruction of the …

We study operator spreading in many-body quantum systems by its potential to generate an
informationally complete measurement record in quantum tomography. We adopt …

NOON states, states between two modes of light of the form| N, 0⟩+ e iϕ| 0, N⟩, are highly
nonclassical entangled states with applications in super-resolution interferometry. We show …

The quantum speed limit (QSL) is a theoretical lower bound of the time required for a
quantum system to evolve from an arbitrary initial state to its orthogonal counterpart. This …

The article establishes a framework for dynamic generation of informationally complete
POVMs in quantum state tomography. Assuming that the evolution of a quantum system is …

Quantum process tomography is the task of reconstructing unknown quantum channels from
measured data. In this work, we introduce compressed sensing-based methods that facilitate …

Does chaos in the dynamics enable or impede information gain in quantum tomography?
We address this question by considering continuous measurement tomography in which the …
