Quantum Computing with Quantum Dots
This paper presents what the researchers have discovered for three types of systems: exciton systems, electron spin systems, and nuclear spin systems and investigates the role that polarons play in the decoherence of spin systems.
Abstract
Our time at the Computing Beyond Silicon Summer School, hosted by Caltech, gave us a unique opportunity to explore new concepts and learn about advances in modern information processing that interest us. We chose to study quantum computation using quantum dot systems because of their potential for bringing forth a solid-sate quantum information processing system. Specifically we chose to investigate three questions: (1) What physical properties of a quantum dot can be used to carry quantum information? (2) How do we create quantum gates using these systems? (3) How do we create simple quantum circuits using these systems? This paper presents what we have discovered for three types of systems: exciton systems, electron spin systems, and nuclear spin systems. We also investigate the role that polarons play in the decoherence of spin systems.
