Microwave Networks for Solid State Quantum Information Processors

Abstract: Quantum computing is a radically new approach to processing information. It is one of the approaches which has the potential to address the ever-growing need of society, industry and research for computing power. At ETH Zurich, we have designed, realized and tested a first data link which allows superconducting-circuit-based quantum processors located in different systems to directly exchange quantum information [1]. This link, for a quantum computer, takes the role of a network transferring data between computing nodes located in a high-performance computing data center. However, unlike its conventional counterparts, our data link is operated at ultra-low temperatures, close to the absolute zero. This allows our quantum data link to directly connect to quantum processors operating at the same temperature [2]. The system we have constructed is a first of its kind in the world and could play an important role in growing the power of quantum computers in the future.
