Exploring More-Coherent Quantum Annealing

Understand

In the quest to reboot computing, quantum annealing (QA) is an interesting candidate for a new capability.

• While it has not demonstrated an advantage over classical computing on a real-world application, many important regions of the QA design space have yet to be explored.
• In IARPA's Quantum Enhanced Optimization (QEO) program, we have opened some new lines of inquiry to get to the heart of QA, and are designing testbed superconducting circuits and conducting key experiments.
• In this paper, we discuss recent experimental progress related to one of the key design dimensions: qubit coherence.
