A Bird's Eye View on Quantum Computing: Current and Future Trends

Quantum computing is a potentially highly-disruptive technology for several domains across the Computer Science field. However, many technological challenges still prevent the construction of a fault-tolerant and reliable quantum computer. These challenges sparked enormous interest in the scientific community, which led to the development of several independent strands of research. Consequently, research in the quantum computing domain is fragmented, making it highly specialized. This can lead to missed opportunities in identifying valuable research directions and contributions from neighboring research areas. For these reasons, this paper provides an overview of the current state of play in quantum computing for different quantum research areas at different layers of the development stack. Furthermore, for each of them, we highlight possible new outlooks that could be pivotal in the near future.
