Monogamy of Mutual Information in Graph States
Jesus Fuentes, Cynthia Keeler, William Munizzi +1
The monogamy of mutual information (MMI) is a quantum entropy inequality that enforces the non-positivity of tripartite information. We investigate the failure of MMI in graph stat…

Uniqueness of Complementary Recovery in Holographic Error-Correcting Codes
Julia Jones, Jason Pollack
Holographic codes are a type of error-correcting code with extra geometric structure ensured by a ``complementary recovery'' property: given a division of the physical Hilbert spac…

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…
