Quantum computing at the quantum advantage threshold: a down-to-business review

Understand

It is expected that quantum computers would enable solving various problems that are beyond the capabilities of the most powerful current supercomputers, which are based on classical technologies.

• In the last three decades, advances in quantum computing stimulated significant interest in this field from industry, investors, media, executives, and general public.
• However, the understanding of this technology, its current capabilities and its potential impact in these communities is still lacking.
• Closing this gap requires a complete picture of how to assess quantum computing devices' performance and estimate their potential, a task made harder by the variety of quantum computing models and physical platforms.
