The double-scaled limit of the Sachdev-Ye-Kitaev (SYK) model takes the number of fermions
and their interaction number to infinity in a coordinated way. In this limit, two entangled …

This tutorial article introduces the physics of quantum information scrambling in quantum
many-body systems. The goals are to understand how to precisely quantify the spreading of …

Quantum scrambling describes the spreading of information into many degrees of freedom
in quantum systems, such that the information is no longer accessible locally but becomes …

With the long-term goal of studying models of quantum gravity in the lab, we propose
holographic teleportation protocols that can be readily executed in table-top experiments …

Wormholes are intriguing classical solutions in General Relativity, that have fascinated
theoretical physicists for decades. In recent years, especially in Holography, gravitational …

We present a summary of recent progress and remaining challenges in applying the
methods and ideas of quantum information theory to the study of quantum field theory and …

A bstract According to holography, entanglement is the building block of spacetime;
therefore, drastic changes of entanglement will lead to interesting transitions in the dual …

The quantum dynamics of spin systems with uniform all-to-all interaction are often studied in
the totally symmetric space (TSS) of maximal total spin. However, the TSS states are atypical …

A bstract It has been proposed that the exponential decay and subsequent power law
saturation of out-of-time-order correlation functions can be universally described by …

The dynamics of quantum systems unfolds within a subspace of the state space or operator
space, known as the Krylov space. This review presents the use of Krylov subspace …
