Distributed Quantum Computing: Applications and Challenges
摘要
Quantum computing is presently undergoing rapid development to achieve a significant speed-up promised in certain applications. Nonetheless, scaling quantum computers remains a formidable engineering challenge, prompting exploration of alternative methods to achieve the promised quantum advantage. An example is given by the concept of distributed quantum computing, which aims to scale quantum computers through the linking of different individual quantum computers. Additionally, distributed quantum computing opens the way to new applications on the longer term. This study seeks to give an overview of this technology on an application-level, considering both use cases, opportunities, challenges and implementation considerations. This is done by combining a thorough literature review and industry overview with distributed quantum computing implementation experiences from the authors. In this way, this work aims to push forward the field of distributed quantum computing, aiming for real-world distributed quantum systems in the near future.
