Belief Propagation-based Disentanglers for Tensor Network State Preparation
Tomasz Szołdra, Peter Schmelcher
We develop a quantum circuit synthesis method for preparing a class of tensor network states. The scheme applies to states tractable with belief propagation (BP), a tensor network…

Scalable Preparation of Matrix Product States with Sequential and Brick Wall Quantum Circuits
Tomasz Szołdra, Rick Mukherjee, Peter Schmelcher
Preparing arbitrary quantum states requires exponential resources. Matrix Product States (MPS) admit more efficient constructions, particularly when accuracy is traded for circuit…

Fidelity and Overlap of Neural Quantum States: Error Bounds on the Monte Carlo Estimator
Tomasz Szołdra
Overlap between two neural quantum states can be computed through Monte Carlo sampling by evaluating the unnormalized probability amplitudes on a subset of basis configurations. Du…
