Probing entanglement scaling across a quantum phase transition on a quantum computer
Qiang Miao, Tianyi Wang, Kenneth R. Brown +2
The investigation of strongly-correlated quantum matter is difficult due to the curse of dimensionality and intricate entanglement structures. These challenges are particularly pro…
Equivalence of cost concentration and gradient vanishing for quantum circuits: An elementary proof in the Riemannian formulation
Qiang Miao, Thomas Barthel
The optimization of quantum circuits can be hampered by a decay of average gradient amplitudes with increasing system size. When the decay is exponential, this is called the barren…
Isometric tensor network optimization for extensive Hamiltonians is free of barren plateaus
Qiang Miao, Thomas Barthel
We explain why and numerically confirm that there are no barren plateaus in the energy optimization of isometric tensor network states (TNS) for extensive Hamiltonians with finite-…
Absence of barren plateaus and scaling of gradients in the energy optimization of isometric tensor network states
Thomas Barthel, Qiang Miao
Vanishing gradients can pose substantial obstacles for high-dimensional optimization problems. Here we consider energy minimization problems for quantum many-body systems with exte…
Convergence and Quantum Advantage of Trotterized MERA for Strongly-Correlated Systems
Qiang Miao, Thomas Barthel
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…
