We present the first protocol allowing a classical computer to
interactively verify the result of an efficient quantum
computation. We achieve this by constructing a measurement
protocol, which allows a classical string to serve as a commitment
to a...
These were originally discovered by Sen (see hep-th/9808141,
hep-th/9809111, hep-th/9904207, for example). Another interesting
paper is by Kraus and Larsen, hep-th/0012198.
I will describe a new perspective based on anomalies.
We compute the local second variation of the von Neumann entropy of
a region in theories with a gravity dual. For null variations our
formula says that the diagonal part of the Quantum Null Energy
Condition is saturated in every state, thus...
I will give introduction to general integrability-based methods to
study two-dimensional quantum field theories. The goal (which I
don't think I will achieve) is to explain how to compute the
boundary entropy (also known as "g-function"), which...
I will show how the $T\bar T$ deformation of a two-dimensional QFT
is related to coupling this QFT to a certain gravitational theory.
This theory provides a natural set of clocks and rods which allow
to define and compute the partition function on a...
I will review the averaged null energy condition, the Markov
property and the quantum null energy condition in quantum field
theory from an information-theoretic point of view. I will give
some explicit examples from finite quantum systems and free...
I will discuss particle physics phenomenology from the point of
view of statistical inference.
I will describe how the concept of information geometry can be used
to equip the parameter space of a theory with a metric.
The central object in this...
It is recently recognized that the global symmetry of a theory can
be a nontrivial mixture of 0-form and 1-form global symmetries,
called 2-group symmetry. A place where 2-group symmetry
ubiquitously exists is 6d N=(1,0) little string theories. In...
