Qubit Feedback on a Five-Qubit Transmon Device

ORAL

Abstract

Feedback-based dynamic control of quantum processors is a key component for many medium-to-large-scale quantum information processing routines. Several groups have begun addressing this need, often using in-house, custom-built hardware. We have implemented real-time feedback for superconducting qubits using scalable, programmable and commercially available hardware from Keysight Technologies. We will use this hardware to implement a multi-qubit reset protocol and to demonstrate a three-qubit bit-flip error detection code on a five-qubit transmon device. I will present our latest experimental progress towards this goal.
