TOPIC: Online quantum computing

Abstract
The operation of real quantum computers, including the implementation and characterization of a given quantum circuit or algorithm, has until recently been carried out exclusively by the experimental groups that design and make the hardware. However IBM, Rigetti, and Alibaba have recently opened their superconducting chips to the research community, and Google and IonQ have announced similar plans. The field is approaching a transition where a significant amount of quantum computing research and development can be performed online. An online presence is especially important now because there are critical questions facing the realization of quantum computers that benefit from wide community input and experimentation. In this talk I'll give an overview of our online quantum computing research, and discuss recent work on the Josephson sampler circuit (M. R. Geller, Phys. Rev. Applied 10, 024052), used to embed classical information into a chain of qubits, and on the measurement of the relative robustness of two families of entangled states, GHZ states and linear cluster states (A. Katabarwa and M. R. Geller, 1808.05203). I'll also discuss opportunities for interesting future work on error measurement and modeling.
