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 …

The standard description of quantum mechanics considers the time-evolution of isolated
quantum systems whose unitary dynamics are governed by the Schrödinger equation …

In almost all quantum applications, one of the key steps is to verify that the fidelity of the
prepared quantum state meets expectations. In this Letter, we propose a new approach …

We study quantum process tomography given the prior information that the map is a unitary
or close to a unitary process. We show that a unitary map on ad-level system is completely …

We apply the method of compressed sensing (CS) quantum process tomography (QPT) to
characterize quantum gates based on superconducting Xmon and phase qubits. Using …

We realize a mechanical analogue of the Dicke model, achieved by coupling the spin of
individual neutral atoms to their quantized motion in an optical trapping potential. The atomic …

Quantum state tomography suffers from the measurement effort increasing exponentially
with the number of qubits. Here, we demonstrate permutationally invariant tomography for …

We implement arbitrary maps between pure states in the 16-dimensional Hilbert space
associated with the ground electronic manifold of Cs 133. This is accomplished by driving …

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

Estimating the parameters that dictate the dynamics of a quantum system is an important
task for quantum information processing and quantum metrology, as well as fundamental …
