This question already has an answer here:
According to the press information from Dwave, quantum annealing is up and running and offers a lot of opportunities for society. “Basically, a quantum computer is a non-deterministic turing machine which is exciting and cool” – this is at least the statement of AI influencer Siraj Raval who has researched the topic in detail. He has made a video about the subject and is trying to communicte the subject to larger audience. Dwave itself is also interested in promoting their product. They have a lot of information out there and some companies are using these machines, for example Google.
But what i didn't understand is, why exactly do society needs a quantum computer? I mean, image recognition and robotics control can be done with classical deeplearning on mainstream hardware, why do we need superposition and qubits. Or asking more directly, which challenges are out there, that only quantum computers are able to master it?
