Quantum annealing speedup of embedded problems via suppression of Griffiths singularities
Sergey Knysh, Eugeniu Plamadeala, Davide Venturelli
Optimal parameter setting for applications problems embedded into hardware graphs is key to practical quantum annealers (QA). Embedding chains typically crop up as harmful Griffith…
From Ansätze to Z-gates: a NASA View of Quantum Computing
Eleanor G. Rieffel, Stuart Hadfield, Tad Hogg +12
For the last few years, the NASA Quantum Artificial Intelligence Laboratory (QuAIL) has been performing research to assess the potential impact of quantum computers on challenging…
Scrambling in the Quantum Lifshitz Model
Eugeniu Plamadeala, Eduardo Fradkin
We study signatures of chaos in the quantum Lifshitz model through out-of-time ordered correlators (OTOC) of current operators. This model is a free scalar field theory with dynami…
Topological Enrichment of Luttinger's Theorem
Parsa Bonderson, Meng Cheng, Kaushal Patel +1
We establish a generalization of Luttinger's theorem that applies to fractionalized Fermi liquids, i.e. Fermi liquids coexisting with symmetry enriched topological order. We find t…
Transport in a One-Dimensional Hyperconductor
Eugeniu Plamadeala, Michael Mulligan, Chetan Nayak
We define a `hyperconductor' to be a material whose electrical and thermal DC conductivities are infinite at zero temperature and finite at any non-zero temperature. The low-temper…
Perfect Metal Phases of One-Dimensional and Anisotropic Higher-Dimensional Systems
Eugeniu Plamadeala, Michael Mulligan, Chetan Nayak
We show that a 1D quantum wire with channels of interacting fermions has a perfect metal phase in which all weak perturbations that could destabilize this phase are irrelevant…
Bulk-Edge Correspondence in 2+1-Dimensional Abelian Topological Phases
Jennifer Cano, Meng Cheng, Michael Mulligan +3
The same bulk two-dimensional topological phase can have multiple distinct, fully-chiral edge phases. We show that this can occur in the integer quantum Hall states at and 12…
Short-Range Entangled Bosonic States with Chiral Edge Modes and -duality of Heterotic Strings
Eugeniu Plamadeala, Michael Mulligan, Chetan Nayak
We consider states of bosons in two dimensions that do not support anyons in the bulk, but nevertheless have stable chiral edge modes that are protected even without any symmetry.…
Vortex as a probe - suggested measurement of the order parameter structure in iron-based superconductors
Eugeniu Plamadeala, T. Pereg-Barnea, Gil Refael
Impurities, inevitably present in all samples, induce elastic transitions between quasiparticle states on the contours of constant energy. These transitions may be seen in Fourier…
