Nonlocality in instantaneous quantum circuits
Joel J. Wallman, Emily Adlam
We show that families of Instantaneous Quantum Polynomial (IQP) circuits corresponding to nontrivial Bell tests exhibit nonlocality. However, we also prove that this nonlocality ca…
Characterization of Leakage Errors via Randomized Benchmarking
Joel J. Wallman, Marie Barnhill, Joseph Emerson
Leakage errors arise when the quantum state leaks out of some subspace of interest, for example, the two-level subspace of a multi-level system defining a computational `qubit' or…
Randomized Benchmarking with Confidence
Joel J. Wallman, Steven T. Flammia
Randomized benchmarking is a promising tool for characterizing the noise in experimental implementations of quantum systems. In this paper, we prove that the estimates produced by…
Contextuality supplies the magic for quantum computation
Mark Howard, Joel J. Wallman, Victor Veitch +1
Quantum computers promise dramatic advantages over their classical counterparts, but the answer to the most basic question "What is the source of the power in quantum computing?" h…
