Featured ArXive Papers: September 15th - October 14th, 2019

The noisy-intermediate-scale-quantum (NISQ) Computing newsletter is a curated ArXiv Digest published once a month by the USRA Research Institute for Advanced Computer Science. We feature exclusively experiments and algorithms that advance the field of applied quantum computing in existing hardware. The team of editors collaborates with the NASA Ames Quantum Artificial Intelligence Laboratory (QuAIL) to produce the content.
