SUMMARY:Tunable control and readout of quantum dot hybrid qubits\, Pre
 liminary Exam\, Jared Benson
DESCRIPTION:In this talk\, I will discuss three projects that utilize 
 the tunability of the semiconductor quantum dot platform to enhance th
 e characteristics of the quantum dot hybrid qubit (QDHQ). The first pr
 oject involves the use of dynamic tunnel rate control and latched read
 out to enable single-shot readout and coherent manipulation of the QDH
 Q. Next\, I will present a method in which we use near-infrared illumi
 nation in the presence of applied gate biases to tune the device opera
 ting voltages to be smaller and more uniform. Last\, I will outline ou
 r ongoing efforts to demonstrate a QDHQ with hole spins instead of ele
 ctron spins\, which offers a tunable qubit energy splitting that can b
 e adjusted by changing the confinement of the quantum dots. These proj
 ects represent meaningful steps towards the first experimental realiza
 tion of a two-qubit interaction between quantum dot hybrid qubits.
