Quasi-quantum states and the quasi-quantum PCP theorem
Itai Arad, Miklos Santha
We introduce -local quasi-quantum states: a superset of the regular quantum states, defined by relaxing the positivity constraint. We show that a -local quasi-quantum state o…

On the dynamical Lie algebras of quantum approximate optimization algorithms
Jonathan Allcock, Miklos Santha, Pei Yuan +1
Dynamical Lie algebras (DLAs) have emerged as a valuable tool in the study of parameterized quantum circuits, helping to characterize both their expressiveness and trainability. In…

Beyond Bell sampling: stabilizer state learning and quantum pseudorandomness lower bounds on qudits
Jonathan Allcock, Joao F. Doriguello, Gábor Ivanyos +1
Bell sampling is a simple yet powerful measurement primitive that has recently attracted a lot of attention, and has proven to be a valuable tool in studying stabiliser states. Unf…
