Abstract: Quantum information processing (QIP) has recently reached a new level of maturity, marked by the ability to manufacture small yet fully functional quantum computers. Specifically, universal programmable quantum computers have been demonstrated by the researchers at UMD (trapped-ion QIP) and IBM (superconducting-circuit QIP), both about a year and a half ago. Further rapid progress in scaling these platforms, as well as other relevant ones, is anticipated. Google, for instance, is openly speaking about their plans to deliver a 49-qubit quantum computer in as soon as a few to several months.

In this talk, I will discuss how to program a trapped-ion quantum computer to efficiently execute arbitrary abstract quantum algorithms. Specifically, I will focus on the techniques and algorithms used to optimize resources (gate counts, fidelity, runtime) in the implementation of quantum algorithms. I will show experimental data, including the results of benchmarking the UMD trapped-ion 5-qubit computer against the IBM superconducting quantum computer, as well as how to use the trapped-ion quantum computer to win a game with a negative classical value.
