Abstract
This talk explores the evolving landscape of computational technology in High-Energy Physics (HEP), tracing the journey from established methods to novel quantum solutions. We begin with a brief overview of research topics utilizing classical CPUs and GPUs, including techniques like traditional AI, Monte Carlo event generators, and integration algorithms.
The core of the presentation transitions to novel quantum technologies, focusing specifically on quantum computing for challenging HEP applications, such as calculating Parton Distribution Functions and enhancing event generation. We will focus on the software front by introducing Qibo, the open-source quantum computing framework co-developed in Singapore. We will showcase new results demonstrating its application in Quantum Machine Learning (QML), highlighting its potential to accelerate complex tasks in HEP.
We conclude by summarizing the current status and outlining the compelling research opportunities for quantum applications being explored within the Centre for Quantum Technologies (CQT).
