With the rapid development of quantum technologies, a pressing need has emerged for a
wide array of tools for the certification and characterization of quantum devices. Such tools …

Gate set tomography (GST) is a protocol for detailed, predictive characterization of logic
operations (gates) on quantum computing processors. Early versions of GST emerged …

Quantum tomography is currently ubiquitous for testing any implementation of a quantum
information processing device. Various sophisticated procedures for state and process …

Quantum process tomography is a necessary tool for verifying quantum gates and
diagnosing faults in architectures and gate design. We show that the standard approach of …

Photosynthetic units perform energy transfer remarkably well under a diverse range of
demanding conditions. However, the mechanism of energy transfer, from excitation to …

We introduce and demonstrate experimentally:(1) a framework called" gate set
tomography"(GST) for self-consistently characterizing an entire set of quantum logic gates …

Quantum tomography has come a long way from early reconstructions of Wigner functions
from projections along quadratures to the full characterization of multipartite systems. Now, it …

Traditional methods of quantum state characterization are impractical for systems of more
than a few qubits due to exponentially expensive postprocessing and data storage and lack …

State and measurement tomography make assumptions about the experimental states or
measurements. These assumptions are often not justified because state preparation and …

Hybrid classical quantum optimization methods have become an important tool for efficiently
solving problems in the current generation of noisy intermediate-scale quantum computers …
