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…
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…
