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…
Solving lattice gauge theories using the quantum Krylov algorithm and qubitization
Lewis W. Anderson, Martin Kiffner, Tom O'Leary +2
Computing vacuum states of lattice gauge theories (LGTs) containing fermionic degrees of freedom can present significant challenges for classical computation using Monte-Carlo meth…
