The Challenge of Controlling a Quantum Computer

​Quantum computers are anticipated to solve particular computational tasks from factoring to molecular simulations substantially faster than conventional computers. Depending on the task, such quantum computers need to be composed of hundreds to millions of qubits, the principal building blocks of a quantum processor. Present-day quantum processors comprise tens of qubits and are not yet able to execute any meaningful computations due to, among others, a lack of scalable and precise calibration and control techniques. In this presentation, Benjamin will discuss the challenges of controlling and calibrating quantum systems and why realizing the promise of quantum computers depends on efficient and robust quantum control routines.
