Anticoncentration and state design of random tensor networks

G Lami, J De Nardis, X Turkeshi - arxiv preprint arxiv:2409.13023, 2024 - arxiv.org
We investigate quantum random tensor network states where the bond dimensions scale
polynomially with the system size, $ N $. Specifically, we examine the delocalization …

Beyond Bell sampling: stabilizer state learning and quantum pseudorandomness lower bounds on qudits

J Allcock, JF Doriguello, G Ivanyos… - arxiv preprint arxiv …, 2024 - arxiv.org
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. Unfortunately …

Pseudorandom quantum authentication

T Haug, N Bansal, WK Mok, DE Koh… - arxiv preprint arxiv …, 2025 - arxiv.org
We introduce the pseudorandom quantum authentication scheme (PQAS), an efficient
method for encrypting quantum states that relies solely on the existence of pseudorandom …

Tolerant Testing of Stabilizer States with Mixed State Inputs

V Iyer, D Liang - arxiv preprint arxiv:2411.08765, 2024 - arxiv.org
We study the problem of tolerant testing of stabilizer states. In particular, we give the first
such algorithm that accepts mixed state inputs. Formally, given a mixed state $\rho $ that …
