Probing context-dependent errors in quantum processors
Kenneth Rudinger, Timothy Proctor, Dylan Langharst +3
Gates in error-prone quantum information processors are often modeled using sets of one- and two-qubit process matrices, the standard model of quantum errors. However, the results…
Maximum likelihood quantum state tomography is inadmissible
Christopher Ferrie, Robin Blume-Kohout
Maximum likelihood estimation (MLE) is the most common approach to quantum state tomography. In this letter, we investigate whether it is also optimal in any sense. We show that ML…
Direct randomized benchmarking for multi-qubit devices
Timothy J. Proctor, Arnaud Carignan-Dugas, Kenneth Rudinger +3
Benchmarking methods that can be adapted to multi-qubit systems are essential for assessing the overall or "holistic" performance of nascent quantum processors. The current industr…
