A Unified Graph-Theoretic Framework for Free-Fermion Solvability
Adrian Chapman, Samuel J. Elman, Ryan L. Mann
We show that a quantum spin system has an exact description by non-interacting fermions if its frustration graph is claw-free and contains a simplicial clique. The frustration grap…
Free-Fermion Subsystem Codes
Adrian Chapman, Steven T. Flammia, Alicia J. Kollár
We consider quantum error-correcting subsystem codes whose gauge generators realize a translation-invariant, free-fermion-solvable spin model. In this setting, errors are suppresse…
Free fermions behind the disguise
Samuel J. Elman, Adrian Chapman, Steven T. Flammia
An invaluable method for probing the physics of a quantum many-body spin system is a mapping to noninteracting effective fermions. We find such mappings using only the frustration…
Characterization of solvable spin models via graph invariants
Adrian Chapman, Steven T. Flammia
Exactly solvable models are essential in physics. For many-body spin-1/2 systems, an important class of such models consists of those that can be mapped to free fermions hopping on…
Many-body-localization transition in a universal quantum circuit model
Adrian Chapman, Akimasa Miyake
The dynamical generation of complex correlations in quantum many-body systems is of renewed interest in the context of quantum chaos, where the out-of-time-ordered (OTO) correlatio…
Classical simulation of quantum circuits by dynamical localization: analytic results for Pauli-observable scrambling in time-dependent disorder
Adrian Chapman, Akimasa Miyake
We extend the concept of Anderson localization, the confinement of quantum information in a spatially irregular potential, to quantum circuits. Considering matchgate circuits, gene…
How an autonomous quantum Maxwell demon can harness correlated information
Adrian Chapman, Akimasa Miyake
We study an autonomous quantum system which exhibits refrigeration under an information-work trade-off like a Maxwell demon. The system becomes correlated as a single "demon" qubit…
Toward Early-Warning Detection of Gravitational Waves from Compact Binary Coalescence
Kipp Cannon, Romain Cariou, Adrian Chapman +11
Rapid detection of compact binary coalescence (CBC) with a network of advanced gravitational-wave detectors will offer a unique opportunity for multi-messenger astronomy. Prompt de…
Singular value decomposition applied to compact binary coalescence gravitational-wave signals
Kipp Cannon, Adrian Chapman, Chad Hanna +3
We investigate the application of the singular value decomposition to compact-binary, gravitational-wave data-analysis. We find that the truncated singular value decomposition redu…
