P15 – Diagnostics of quantum devices
Borivoje Dakic
Abstract:
Abstract:
Quantum systems will only ever be as useful as the information we can extract from them. Quantum diagnostic protocols that enable efficient and reliable interrogation of such quantum devices are as important as the devices themselves with their massive dimension and sensitivity to noise, leading to a rather unique challenge. We have produced protocols that allow for the extraction of exponential amounts of (physically relevant) information with a resource, memory, and computational complexity that is largely independent of the size of the system. Our research aims to create a unified theory for diagnosing large-scale quantum systems, focusing on verification, certification, and characterization protocols—critical tools for advancing next-generation quantum technologies.
