Operational, gauge-free quantum tomography
Olivia Di Matteo, John Gamble, Chris Granade +2
As increasingly impressive quantum information processors are realized in laboratories around the world, robust and reliable characterization of these devices is now more urgent th…
Bayesian ACRONYM Tuning
John Gamble, Chris Granade, Nathan Wiebe
We provide an algorithm that uses Bayesian randomized benchmarking in concert with a local optimizer, such as SPSA, to find a set of controls that optimizes that average gate fidel…
Direct observation of quantum criticality in Ising spin chains
Jingfu Zhang, Fernando M. Cucchietti, C. M. Chandrashekar +6
We use NMR quantum simulators to study antiferromagnetic Ising spin chains undergoing quantum phase transitions. Taking advantage of the sensitivity of the systems near criticality…
Foundations of Quantum Decoherence
John Gamble
The conventional interpretation of quantum mechanics, though it permits a correspondence to classical physics, leaves the exact mechanism of transition unclear. Though this was onl…
