Scalable Quantum Optimal Control

Executive Summary

To address one of the fundamental challenges in quantum computing, we will develop a massively parallel solver that will finally enable control over the quantum states of a device. Developing this technology will accelerate the realization of practical high-performance quantum computing technologies and will help position the United States as a world leader in the emerging fields of quantum sensing, control, and scientific quantum computing.
