Quantum Computing has the potential to transform science. Quantum computers will be able to solve important problems that today’s most powerful supercomputers cannot. Fast and precise control of quantum computers is needed to increase their accuracy and practical usage.

High-quality building blocks (qudits) and scaling up hardware for quantum information processing are critical requirements for quantum processors to achieve practical utility. A key challenge is the sustained precision control of large quantum systems. Many current quantum computer architectures consist of a layered control stack between algorithms and physical implementation. Scaling up requires optimization of pulses and communication between the layers. Efficient, accurate, and sometimes large-scale classical simulations of quantum devices provide a necessary glue between the layers, allowing for the practical generation of quantum optimal control pulses.

In this talk, I will discuss the challenges of closing the gap between quantum computing technology and applications. Quantum control can play an important role to close the gap. I will discuss steps towards it from my research.
