Low-depth gradient measurements can improve convergence in variational hybrid quantum-classical algorithms
Aram Harrow, John Napp
A broad class of hybrid quantum-classical algorithms known as "variational algorithms" have been proposed in the context of quantum simulation, machine learning, and combinatorial…

Optimal Bacon-Shor codes
John Napp, John Preskill
We study the performance of Bacon-Shor codes, quantum subsystem codes which are well suited for applications to fault-tolerant quantum memory because the error syndrome can be extr…
