Solving quasi-free and quadratic Lindblad master equations for open fermionic and bosonic systems
Thomas Barthel, Yikang Zhang
The dynamics of Markovian open quantum systems are described by Lindblad master equations. For fermionic and bosonic systems that are quasi-free, i.e., with Hamiltonians that are q…

Quantum-classical eigensolver using multiscale entanglement renormalization
Qiang Miao, Thomas Barthel
We propose a variational quantum eigensolver (VQE) for the simulation of strongly-correlated quantum matter based on a multi-scale entanglement renormalization ansatz (MERA) and gr…

On the closedness and geometry of tensor network state sets
Thomas Barthel, Jianfeng Lu, Gero Friesecke
Tensor network states (TNS) are a powerful approach for the study of strongly correlated quantum matter. The curse of dimensionality is addressed by parametrizing the many-body sta…
