Erasure conversion in Majorana qubits via local quasiparticle detection
Abhijeet Alase, Kevin D. Stubbs, Barry C. Sanders +1
Quasiparticle poisoning errors in Majorana-based qubits are not suppressed by the underlying topological properties, which undermines the usefulness of this proposed platform. This…
Interacting models for twisted bilayer graphene: a quantum chemistry approach
Fabian M. Faulstich, Kevin D. Stubbs, Qinyi Zhu +7
The nature of correlated states in twisted bilayer graphene (TBG) at the magic angle has received intense attention in recent years. We present a numerical study of an interacting…
Algebraic localization of Wannier functions implies Chern triviality in non-periodic insulators
Jianfeng Lu, Kevin D. Stubbs
For gapped periodic systems (insulators), it has been established that the insulator is topologically trivial (i.e., its Chern number is equal to ) if and only if its Fermi proj…
Algebraic localization implies exponential localization in non-periodic insulators
Jianfeng Lu, Kevin D. Stubbs
Exponentially-localized Wannier functions are a basis of the Fermi projection of a Hamiltonian consisting of functions which decay exponentially fast in space. In two and three spa…
The Iterated Projected Position Algorithm for Constructing Exponentially Localized Generalized Wannier Functions for Periodic and Non-Periodic Insulators in Two Dimensions and Higher
Kevin D. Stubbs, Alexander B. Watson, Jianfeng Lu
Localized bases play an important role in understanding electronic structure. In periodic insulators, a natural choice of localized basis is given by the Wannier functions which de…
Reinforcement Learning with Neural Networks for Quantum Multiple Hypothesis Testing
Sarah Brandsen, Kevin D. Stubbs, Henry D. Pfister
Reinforcement learning with neural networks (RLNN) has recently demonstrated great promise for many problems, including some problems in quantum information theory. In this work, w…
Existence and computation of generalized Wannier functions for non-periodic systems in two dimensions and higher
Jianfeng Lu, Kevin D. Stubbs, Alexander B. Watson
Exponentially-localized Wannier functions (ELWFs) are an orthonormal basis of the Fermi projection of a material consisting of functions which decay exponentially fast away from th…
Adaptive Procedures for Discrimination Between Arbitrary Tensor-Product Quantum States
Sarah Brandsen, Mengke Lian, Kevin D. Stubbs +2
Discrimination between quantum states is a fundamental task in quantum information theory. Given two arbitrary tensor-product quantum states (TPQS) $ρ_{\pm} = ρ_{\pm}^{(1)} \otimes…
Phase Diagrams of Single Layer Two-Dimensional Transition Metal Dichalcogenides: Landau Theory
Anna N. Morozovska, Eugene A. Eliseev, Kevin D. Stubbs +3
Single layer (SL) two-dimensional transition metal dichalcogenides (TMDs), such as MoS2, ReS2, WSe2, and MoTe2 have now become the focus of intensive fundamental and applied resear…
On discrete Wigner transforms
Zhenning Cai, Jianfeng Lu, Kevin Stubbs
In this work, we derive a discrete analog of the Wigner transform over the space for any prime and any positive integer . We show that the Wigne…
Discrete Directional Gabor Frames
Wojciech Czaja, Benjamin Manning, James M. Murphy +1
We develop a theory of discrete directional Gabor frames for functions defined on the -dimensional Euclidean space. Our construction incorporates the concept of ridge functions…
