Entanglement in the quantum phases of an unfrustrated Rydberg atom array

  title={Entanglement in the quantum phases of an unfrustrated Rydberg atom array},
  author={Matthew J. O’Rourke and Garnet Kin-Lic Chan},
We report on the ground state phase diagram of interacting Rydberg atoms in the unfrustrated square lattice array. Using new tensor network algorithms, we scale to large systems in two dimensions while including all long-range interactions, revealing the phases in the bulk and their analogs in accessible finite arrays. We find a greatly altered phase diagram from earlier numerical and experimental studies, and in particular, we uncover an emergent entangled quantum nematic phase that appears in…

Is there evidence for exponential quantum advantage in quantum chemistry?

The idea to use quantum mechanical devices to simulate other quantum systems is commonly ascribed to Feynman. Since the original suggestion, concrete proposals have appeared for simulating molecular



Exponential Sum Approximations for t − β

Given β > 0 and δ > 0, the function t−β may be approximated for t in a compact interval [δ, T] by a sum of terms of the form we−at, with parameters w > 0 and a > 0. One such an approximation, studied

The ITensor Software Library for Tensor Network Calculations

The philosophy behind ITensor, a system for programming tensor network calculations with an interface modeled on tensor diagrams, and examples of each part of the interface including Index objects, the ITensor product operator, tensor factorizations, and tensor storage types are discussed.
