Tensor-network simulation of quantum phase estimation in the von Neumann measurement formulation with DMRG-prepared initial states
The von Neumann measurement formulation of quantum phase estimation [Phys.\ Rev.\ A \textbf{66}, 032314 (2002); Quantum \textbf{5}, 465 (2021)] estimates energies by coupling the system to a discretized pointer register through $\hat H\otimes\hat p$ and reading out the pointer after an inverse quant
