Quantum entropy and central limit theorem

K Bu, W Gu, A Jaffe - … of the National Academy of Sciences, 2023 - National Acad Sciences
We introduce a framework to study discrete-variable (DV) quantum systems based on qudits.
It relies on notions of a mean state (MS), a minimal stabilizer-projection state (MSPS), and a …

Anyonic chains, topological defects, and conformal field theory

M Buican, A Gromov - Communications in Mathematical Physics, 2017 - Springer
Motivated by the three-dimensional topological field theory/two-dimensional conformal field
theory (CFT) correspondence, we study a broad class of one-dimensional quantum …

Discrete quantum Gaussians and central limit theorem

K Bu, W Gu, A Jaffe - arXiv preprint arXiv:2302.08423, 2023 - arxiv.org
We introduce a quantum convolution and a conceptual framework to study states in discrete-
variable (DV) quantum systems. All our results suggest that stabilizer states play a role in DV …

Quantum fourier analysis

A Jaffe, C Jiang, Z Liu, Y Ren… - Proceedings of the …, 2020 - National Acad Sciences
Quantum Fourier analysis is a subject that combines an algebraic Fourier transform (pictorial
in the case of subfactor theory) with analytic estimates. This provides interesting tools to …

Entropic quantum central limit theorem and quantum inverse sumset theorem

K Bu, W Gu, A Jaffe - arXiv preprint arXiv:2401.14385, 2024 - arxiv.org
We establish an entropic, quantum central limit theorem and quantum inverse sumset
theorem in discrete-variable quantum systems describing qudits or qubits. Both results are …

Fusion bialgebras and Fourier analysis: analytic obstructions for unitary categorification

Z Liu, S Palcoux, J Wu - Advances in Mathematics, 2021 - Elsevier
We introduce fusion bialgebras and their duals and systematically study their Fourier
analysis. As an application, we discover new efficient analytic obstructions on the unitary …

Planar para algebras, reflection positivity

A Jaffe, Z Liu - Communications in Mathematical Physics, 2017 - Springer
We define a planar para algebra, which arises naturally from combining planar algebras
with the idea of Z _ N ZN para symmetry in physics. A subfactor planar para algebra is a …

[HTML][HTML] Noncommutative uncertainty principles

C Jiang, Z Liu, J Wu - Journal of Functional Analysis, 2016 - Elsevier
The classical uncertainty principles deal with functions on abelian groups. In this paper, we
discuss the uncertainty principles for finite index subfactors which include the cases for finite …

An angle between intermediate subfactors and its rigidity

K Bakshi, S Das, Z Liu, Y Ren - Transactions of the American Mathematical …, 2019 - ams.org
We introduce a new notion of an angle between intermediate subfactors and prove various
interesting properties of the angle and relate it to the Jones index. We prove a uniform $60 …

From skein theory to presentations for Thompson group

Y Ren - Journal of Algebra, 2018 - Elsevier
Jones introduced some unitary representations of Thompson group F constructed from a
given subfactor planar algebra, and all unoriented links arise as matrix coefficients of these …
