In this edition of The Quantum Insider, we take a deeper dive into recent news that Chinese scientists have smashed quantum supremacy with their superconducting qubit device. They previously hit that milestone with a optical circuit device.
The news, which was described in ArXiv, poses almost as many questions as it answers, such as:
- What does this mean for the big picture of quantum technology development?
- Is this a sign that China is “the” quantum leader, rather than “a” quantum leader?
- How is this development related to other quantum technology work recently reported by Chinese scientists and engineers?
- And how does China’s business climate relate to the nation’s scientific climate.
