Quantum information theory is a branch of science at the frontier of physics, mathematics,
and information science, and offers a variety of solutions that are impossible using classical …

Spectral correlations are a powerful tool to study the dynamics of quantum many-body
systems. For Hermitian Hamiltonians, quantum chaotic motion is related to random matrix …

Noise mechanisms in quantum systems can be broadly characterized as either coherent (ie,
unitary) or incoherent. For a given fixed average error rate, coherent noise mechanisms will …

One of the main quests in quantum metrology is to attain the ultimate precision limit with
given resources, where the resources are not only of the number of queries, but more …

Abstract Weak values and Kirkwood–Dirac (KD) quasiprobability distributions have been
independently associated with both foundational issues in quantum theory and advantages …

To understand the typical dynamics of an open quantum system in continuous time, we
introduce an ensemble of random Lindblad operators, which generate completely positive …

We study various methods to generate ensembles of random density matrices of a fixed size
N, obtained by partial trace of pure states on composite systems. Structured ensembles of …

A bstract The principle of maximum ignorance posits that the coarse-grained description of a
system is maximally agnostic about its underlying microscopic structure. We briefly review …

The survival probability of an initial Coherent Gibbs State (CGS) is a natural extension of the
Spectral Form Factor (SFF) to open quantum systems. To quantify the interplay between …

In recent years, Bayesian methods have been proposed as a solution to a wide range of
issues in quantum state and process tomography. State-of-the-art Bayesian tomography …
