[HTML][HTML] Subsystem symmetries, quantum cellular automata, and computational phases of quantum matter
Quantum phases of matter are resources for notions of quantum computation. In this work,
we establish a new link between concepts of quantum information theory and condensed …

Efficient variational contraction of two-dimensional tensor networks with a non-trivial unit cell
Tensor network states provide an efficient class of states that faithfully capture strongly
correlated quantum models and systems in classical statistical mechanics. While tensor …

Sampling and the complexity of nature
D Hangleiter - arxiv preprint arxiv:2012.07905, 2020 - arxiv.org
Randomness is an intrinsic feature of quantum theory. The outcome of any quantum
measurement will be random, sampled from a probability distribution that is defined by the …

Topological order in higher composites
E Babaev - Physical Review Research, 2024 - APS
We introduce the concept of composite topological order in multicomponent systems. In such
a state topological order appears only in higher-than-usual composites, with no topological …
