We expect quantum computers to outperform binary computers by an order of magnitude. But today, they are still quite experimental and only work on small scales. So, this article (dating back to October) is amazing news: Physicist Zhaokai Li and his team from the University of Science and Technology of China in Hefei realized a Handwriting OCR on a quantum computer which means they created the first demonstration of Artificial Intelligence (in the meaning of machine learning) for a quantum computer:
That’s an interesting result for artificial intelligence and more broadly for quantum computing. It demonstrates the potential for quantum computation, not just for character recognition, but for other kinds of big data challenges. “This work paves the way to a bright future where the Big Data is processed efficiently in a parallel way provided by quantum mechanics,” say the team.
