Preparing 100-qubit symmetry-protected topological order on a digital quantum computer
George Pennington, Kevin C. Smith, James R. Garrison +3
Symmetry-protected topological (SPT) phases extend the Landau paradigm of quantum matter by admitting distinct symmetry-preserving phases that lack any local order parameter. Demon…

Symplectic Optimization on Bosonic Gaussian States
Christopher Willby, Tomohiro Hashizume, Jason Crain +1
Computing bosonic Gaussian ground states via variational optimization is challenging because the covariance matrices must satisfy the uncertainty principle, rendering constrained o…

A Quantum Information Perspective on Many-Body Dispersive Forces
Christopher Willby, Martin Kiffner, Joseph Tindall +2
Despite its ubiquity, the quantum many-body properties of dispersion remain poorly understood. Here, we investigate the entanglement distribution in assemblies of quantum Drude osc…
