The theory of entanglement provides a fundamentally new language for describing
interactions and correlations in many-body systems. Its vocabulary consists of qubits and …

Quantum computational complexity estimates the difficulty of constructing quantum states
from elementary operations, a problem of prime importance for quantum computation …

A general scheme is presented for simulating gauge theories, with matter fields, on a digital
quantum computer. A Trotterized time-evolution operator that respects gauge symmetry is …

We consider circuit complexity in certain interacting scalar quantum field theories, mainly
focusing on the ϕ 4theory. We work out the circuit complexity for evolving from a nearly …

Recent progress in studies of holographic dualities, originally motivated by insights from
string theory, has led to a confluence with concepts and techniques from quantum …

A bstract We propose that holographic spacetimes can be regarded as collections of
quantum circuits based on path-integrals. We relate a codimension one surface in a gravity …

We propose a modification to Nielsen's circuit complexity for Hamiltonian simulation using
the Suzuki-Trotter (ST) method, which provides a network like structure for the quantum …

We establish that Polchinski's equation for exact renormalization group (RG) flow is
equivalent to the optimal transport gradient flow of a field-theoretic relative entropy. This …

A bstract In this work we elaborate on holographic description of the path-integral
optimization in conformal field theories (CFT) using Hartle-Hawking wave functions in Anti …

We introduce a new class of states for bosonic quantum fields which extend tensor network
states to the continuum and generalize continuous matrix product states to spatial …
