Quantum science and technology is a new frontier that shows great promise. The ability to control quantum phenomena has far reaching implication for material research, sensing, and computational technologies. Researchers are now routinely controlling individual atoms and making macroscopic quantum circuitry that can be designed to make computational gates. However, oftentimes there is a gap between the ideal quantum systems composed of Rabi oscillations, entanglement, and universal gates, and the typically messy quantum devices made in a lab. In this presentation we will introduce the basics of quantum computing and how they achieve a speedup in computation. We will discuss how we build an artificial atom and why that system behaves like a quantum bit. Finally, we will discuss the sources of noise and decoherence that affect our system and how this leads to a loss of quantum information. This presentation will attempt to give a broad overview of the RF engineering, the material science, and the classical computer science that goes into developing a superconducting quantum computer.
