Scaling of contraction costs for entanglement renormalization algorithms including tensor Trotterization and variational Monte Carlo

Journal Article Physical Review B · January 15, 2025 The multiscale entanglement renormalization ansatz (MERA) is a hierarchical class of tensor network states motivated by the real-space renormalization group. It is used to simulate strongly correlated quantum many-body systems. For prominent MERA structure ... Full text Cite

Convergence and quantum advantage of Trotterized MERA for strongly-correlated systems

Journal Article Quantum · January 1, 2025 Strongly-correlated quantum many-body systems are difficult to study and simulate classically. We recently proposed a variational quantum eigensolver (VQE) based on the multiscale entanglement renormalization ansatz (MERA) with tensors constrained to certa ... Full text Cite

Probing entanglement scaling across a quantum phase transition on a quantum computer

Journal Article arXiv:2412.18602 · December 24, 2024 The investigation of strongly-correlated quantum matter is challenging due to the curse of dimensionality and complex entanglement structures. This complexity is especially pronounced in the vicinity of continuous quantum phase transitions, where quantum f ... Full text Link to item Cite
