Learning and Optimizing Quantum Control Landscapes

This event is part of the Preliminary Oral Exam.

Abstract: The ability to prepare quantum states rapidly and with high fidelity is a crucial step towards fully scalable quantum computers. In this talk I will discuss the existence of phase transitions in the quantum state preparation problem as a function of the constraint parameters (field strengths and ramp time). We study the different phases and discuss their significance in terms of complexity and robustness for the quantum state preparation problem.
