Abstract summary: We advocate a principle of spacetime complexity, where gravity arises as a consequence of spacetime optimizing the computational cost of its own quantum dynamics. We visualize spacetime complexity using Lorentzian threads which represent the operations needed to prepare a quantum state in a tensor network discretizing spacetime.

Abstract: Inspired by the universality of computation, we advocate for a principle of spacetime complexity, where gravity arises as a consequence of spacetime optimizing the computational cost of its own quantum dynamics. This principle is explicitly realized in the context of the Anti-de Sitter/Conformal Field Theory correspondence, where complexity is naturally understood in terms of state preparation via Euclidean path integrals, and Einstein's equations emerge from the laws of quantum complexity. We visualize spacetime complexity using Lorentzian threads which, conceptually, represent the operations needed to prepare a quantum state in a tensor network discretizing spacetime. Thus, spacetime itself evolves via optimized computation.

Unitary Complexity and the Uhlmann Transformation Problem [41.67228730328207]
We introduce a framework for unitary synthesis problems, including notions of reductions and unitary complexity classes. We use this framework to study the complexity of transforming one entangled state into another via local operations. Our framework for unitary complexity thus provides new avenues for studying the computational complexity of many natural quantum information processing tasks.

Circuit Complexity in Topological Quantum Field Theory [0.0]
Quantum circuit complexity has played a central role in advances in holography and many-body physics. In a departure from standard treatments, we aim to quantify the complexity of the Euclidean path integral. We argue that the pants decomposition provides a natural notion of circuit complexity within the category of 2-dimensional bordisms. We use it to formulate the circuit complexity of states and operators in 2-dimensional topological quantum field theory.

We also discuss the question of switching between different internal times as well as the Montevideo interpretation of quantum theory.

The "quantum complexity" of a unitary operator measures the difficulty of its construction from a set of elementary quantum gates. In this paper, we present a unified perspective on various notions of quantum complexity, viewed as functions on the space of unitary operators.
