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 …

We argue that the notion of entanglement in de Sitter space arises naturally from the non-
trivial Lorentzian geometry of the spacetime manifold, which consists of two disconnected …

Despite the fundamental importance of quantum entanglement in many-body systems, our
understanding is mostly limited to bipartite situations. Indeed, even defining appropriate …

A bstract We consider Chern-Simons theory for gauge group G at level k on 3-manifolds M n
with boundary consisting of n topologically linked tori. The Euclidean path integral on M n …

A bstract We study the multi-party entanglement structure of states in Chern-Simons theory
created by performing the path integral on 3-manifolds with linked torus boundaries, called …

Classification of entanglement is an important problem in quantum resource theory. In this
paper we discuss an embedding of this problem in the context of topological quantum field …

A bstract Entanglement is a special feature of the quantum world that reflects the existence
of subtle, often non-local, correlations between local degrees of freedom. In topological …

Quantum circuit complexity has played a central role in recent advances in holography and
many‐body physics. Within quantum field theory, it has typically been studied in a …

We use the Virasoro TQFT to derive an integral identity that we view as a non-rational
generalization of the Verlinde formula for the Virasoro algebra with central charge $ c\geq …

A bstract Topological quantum field theories (TQFT) encode properties of quantum states in
the topological features of abstract manifolds. One can use the topological avatars of …
