13 Quantum Computing with SRF Cavities

The aim of this Section is to summarize in highly simple terms the status and potential applications of quantum computing based on SRF cavities, with a view to exciting prospects for the future. The arrival of SRF-based quantum computing opens pathways to transformative advances.

13.1 Introduction to Quantum Computing

Quantum computing is a fusion of quantum physics and computer science, harnessing the dual phenomena of quantum superposition and quantum entanglement for massive computations. In analogy with “classical computing circuits” called “bits,” the unit of quantum computing is a “qubit.” A bit can be 1 or a 0 since it is just a switch with two possible configurations, “on” or “off.” A classical ...
