Title: Optimal gates in imperfect qubits

Abstract

Designing and operating a quantum computer is subject to a multitude of opposing challenges. In particular, scalable and decoherence-protected solid state quits seem to, at first glance, be very flexible and hard to control. We are going to show how optimal control theory can be used to find pulse shapes for implementing precise and fast gates. Some of these results such as the DRAG technique that avoids leakage to non-computational states can be motivated analytically in a toggling frame.
