Universal computation with magic Hamiltonians
Marius Junge, Jason Pollack, Luke Visser
In the conventional theory of quantum computation, universality is discussed in terms of properties of unitary gate sets. In many experimental setups, however, we instead have acce…
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…
