Operator Algebras and Third Quantization
Yidong Chen, Marius Junge, Nima Lashkari
In quantum gravity, the gravitational path integral involves a sum over topologies, representing the joining and splitting of multiple universes. To account for topology change, on…

Local approximations of global Hamiltonian from inclusion of algebras
Yidong Chen, Nima Lashkari, Kwing Lam Leung
We write down the global Hamiltonian of conformal field theory (CFT) in finite volume in terms of the modular Hamiltonian of the vacuum reduced to a local ball-shaped region, and u…

Resource-Dependent Complexity of Quantum Channels
Roy Araiza, Yidong Chen, Marius Junge +1
We introduce a new framework for quantifying the complexity of quantum channels, grounded in a suitably chosen resource set. This class of convex functions is designed to analyze t…
