Truncating loopy tensor networks by zero-mode gauge fixing
Ihor Sokolov, Yintai Zhang, Jacek Dziarmaga
Loopy tensor networks have internal correlations that often make their compression inefficient. We show that even local bond optimization can make better use of the insight it has…

Kibble-Zurek dynamical scaling hypothesis in the Google analog-digital quantum simulator of the model
Yintai Zhang, Francis A. Bayocboc, Jacek Dziarmaga
State-of-the-art tensor networks are employed to simulate the Hamiltonian ramp in the analog-digital quantum simulation of the quantum phase transition to the quasi-long-range orde…

Bang-bang preparation of quantum many-body ground states in two dimensions: optimization of the algorithm with a two-dimensional tensor network
Yintai Zhang, Jacek Dziarmaga
A bang-bang (BB) algorithm prepares the ground state of a two-dimensional (2D) quantum many-body Hamiltonian by evolving an initial product state alternating between $H…
