We use entangled multimode coherent states to produce entangled giant graviton states, in the context of gauge/gravity duality. We make a smeared distribution of the entangled multimode coherent states on the circle, or on the five-sphere, in the higher dimensional view. In gauge/gravity duality, we analyze the superposition of giant graviton states, and the entangled pairs of giant graviton states. We map a class of angular distribution functions to unitary operations on the pairs. We also use…

Abstract We investigate and characterize the dynamics of operator growth in irrational two-dimensional conformal field theories. By employing the oscillator realization of the Virasoro algebra and
Hidden symmetries and Large N factorisation for permutation invariant matrix observables
Permutation invariant polynomial functions of matrices have previously been studied as the observables in matrix models invariant under SN , the symmetric group of all permutations of N objects. In
Entanglement Entropy and Phase Space Density: Lowest Landau Levels and 1/2 BPS states
We consider the entanglement entropy of an arbitrary subregion in a system of N non-relativistic fermions in 2 + 1 dimensions in Lowest Landau Level (LLL) states. Using the connection of these states


Detecting topology change via correlations and entanglement from gauge/gravity correspondence
We compute a momentum space version of the entanglement spectrum and entanglement entropy of general Young tableau states and one-point functions on Young tableau states. These physical quantities
Superposition induced topology changes in quantum gravity
A bstractWe show that superpositions of classical states in quantum gravity with fixed topology can lead to new classical states with a different topology. We study this phenomenon in a particular
Probing a Gravitational Cat State
We investigate the nature of a gravitational two-state system (G2S) in the simplest setup in Newtonian gravity. In a quantum description of matter a single motionless massive particle can in
From gravitons to giants
We discuss exact quantization of gravitational fluctuations in the half-BPS sector around AdS5 × S5 background, using the dual super Yang-Mills theory. For this purpose we employ the recently
A construction of quarter BPS coherent states and Brauer algebras
BPS coherent states closely resemble semiclassical states and they have gravity dual descriptions in terms of semiclassical geometries. The half BPS coherent states have been well studied, however
Heralded generation of a micro-macro entangled state
Using different optical setups based on squeezed state and photon subtraction we show how optical entanglement between a macroscopic and a microscopic state - the so-called Schrodinger cat state or
Black hole entanglement and quantum error correction
A bstractIt was recently argued in [1] that black hole complementarity strains the basic rules of quantum information theory, such as monogamy of entanglement. Motivated by this argument, we develop

This paper provides a heuristic derivation of how classical gravitational physics in the AdS/CFT correspondence appears from the strong dynamics of the N = 4 SYM theory in a systematic way. We do

Abstract We study target space entanglement in gauged multi-matrix models as models of entanglement between groups of D-branes separated by a planar entangling surface, paying close attention to the
