Quantum Ruzsa Divergence to Quantify Magic
Kaifeng Bu, Weichen Gu, Arthur Jaffe
In this work, we investigate the behavior of quantum entropy under quantum convolution and its application in quantifying magic. We first establish an entropic, quantum central lim…
Stabilizer Testing and Magic Entropy via Quantum Fourier Analysis
Kaifeng Bu, Weichen Gu, Arthur Jaffe
Quantum Fourier analysis is an important topic in mathematical physics. We introduce a systematic protocol for testing and measuring ``magic'' in quantum states and gates, using a…
The Solar Upper Transition Region Imager (SUTRI) onboard the SATech-01 satellite
Xianyong Bai, Hui Tian, Yuanyong Deng +56
The Solar Upper Transition Region Imager (SUTRI) onboard the Space Advanced Technology demonstration satellite (SATech-01), which was launched to a sun-synchronous orbit at a heigh…
Discrete Quantum Gaussians and Central Limit Theorem
Kaifeng Bu, Weichen Gu, Arthur Jaffe
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…
Quantum Entropy and Central Limit Theorem
Kaifeng Bu, Weichen Gu, Arthur Jaffe
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), a…
Möbius disjointness for a class of exponential functions
Weichen Gu, Fei Wei
A vast class of exponential functions are shown to be deterministic. This class includes functions whose exponents are polynomial-like or "piece-wise" close to polynomials after di…
Duality of Graph Invariants
Kaifeng Bu, Weichen Gu, Arthur Jaffe
We study a new set of duality relations between weighted, combinatoric invariants of a graph . The dualities arise from a non-linear transform , acting on the weig…
Computations of Mather Minimal Log Discrepancies
Weichen Gu
We compute the Mather minimal log discrepancy via jet schemes and arc spaces for toric varieties and very general hypersurfaces.
