Gaussian-augmented bosonic matrix-product states: theory and applications
Erickson Tjoa, J. Ignacio Cirac
We propose and analyze the structure of a family of bosonic quantum many-body states that have the following features: (i) they include all pure Gaussian states and finite-dimensio…
Multi-agent Autoformalization of Tensor Network Theory
Sirui Lu, Erickson Tjoa, J. Ignacio Cirac
We build a team of specialized large language-model agents and present an agent-driven workflow for research-level formalization in theoretical physics, with the autoformalization…
Continuous matrix product operators for quantum fields
Erickson Tjoa, J. Ignacio Cirac
In this work we introduce an ansatz for continuous matrix product operators for quantum field theory. We show that (i) they admit a closed-form expression in terms of finite number…
Bipartite and tripartite entanglement in pure dephasing relativistic spin-boson model
Kensuke Gallock-Yoshimura, Erickson Tjoa
We study nonperturbatively the entanglement generation between two and three emitters in an exactly solvable relativistic variant of the spin-boson model, equivalent to the time-in…
Transmission of quantum information through quantum fields in curved spacetimes
Michael Kasprzak, Erickson Tjoa
We construct a relativistic quantum communication channel between two localized qubit systems, mediated by a relativistic quantum field, that can achieve the theoretical maximum fo…
