Bulk-boundary correspondence and singularity-filling in long-range free-fermion chains
Nick G. Jones, Ryan Thorngren, Ruben Verresen
The bulk-boundary correspondence relates topologically-protected edge modes to bulk topological invariants, and is well-understood for short-range free-fermion chains. Although cas…
Quantum Spin Puddles and Lakes: NISQ-Era Spin Liquids from Non-Equilibrium Dynamics
Rahul Sahay, Ashvin Vishwanath, Ruben Verresen
While many-body systems can host long-ranged entangled quantum spin liquids (QSLs), the ingredients for realizing these as ground states can be prohibitively difficult. In many cir…
Higgs Condensates are Symmetry-Protected Topological Phases: I. Discrete Symmetries
Ruben Verresen, Umberto Borla, Ashvin Vishwanath +2
Where in the landscape of many-body phases of matter do we place the Higgs condensate of a gauge theory? On the one hand, the Higgs phase is gapped, has no local order parameter, a…
Hierarchy of topological order from finite-depth unitaries, measurement and feedforward
Nathanan Tantivasadakarn, Ashvin Vishwanath, Ruben Verresen
Long-range entanglement--the backbone of topologically ordered states--cannot be created in finite time using local unitary circuits, or equivalently, adiabatic state preparation.…
Universal measurement-based quantum computation in a one-dimensional architecture enabled by dual-unitary circuits
David T. Stephen, Wen Wei Ho, Tzu-Chieh Wei +2
A powerful tool emerging from the study of many-body quantum dynamics is that of dual-unitary circuits, which are unitary even when read `sideways', i.e., along the spatial directi…
Shortest Route to Non-Abelian Topological Order on a Quantum Processor
Nathanan Tantivasadakarn, Ruben Verresen, Ashvin Vishwanath
A highly coveted goal is to realize emergent non-Abelian gauge theories and their anyonic excitations, which encode decoherence-free quantum information. While measurements in quan…
