Bounding Entanglement Entropy with Clifford Double Cosets
Cynthia Keeler, William Munizzi, Jason Pollack
Following on our previous work arXiv:2204.07593 and arXiv:2306.01043 studying the orbits of quantum states under Clifford circuits via `reachability graphs', we introduce `contract…

Expanding on the double copy in null Fermi coordinates
Samarth Chawla, Kwinten Fransen, Cynthia Keeler
We propose a Weyl classical double copy for a Fermi normal coordinate expansion around null geodesics. To leading order in this "Penrose expansion", we recover a previously propose…
