The Role of Graphene in Advancing Quantum Computing Technologies

Abstract

The advent of quantum computing heralds a transformative shift in computational capabilities, leveraging the principles of quantum mechanics to solve problems intractable for classical computers. Among the myriad of materials investigated for quantum computing, graphene stands out due to its exceptional electronic properties. This paper presents a comprehensive review of the current landscape in graphene-based quantum computing, highlighting the pivotal role of graphene’s ballistic transport, high carrier mobility, and unique band structure in the development of quantum bits (qubits). Focusing on recent advancements, including the integration of graphene into Josephson junctions and circuit quantum electrodynamics (cQED) systems, we analyze the progress and challenges in fabricating graphene-based quantum devices. Through a detailed examination of experimental milestones, particularly the seminal work by Kroll et al. (2018), we assess the potential of graphene to enhance qubit resilience and functionality. We identify key challenges facing the field, such as scalability and qubit coherence, and discuss potential solutions that could pave the way for next-generation quantum computing devices. Concluding with future research directions, this review underscores the necessity for interdisciplinary collaboration to harness graphene’s full potential in quantum computing, offering insights into unsolved problems and emerging technologies.
