• Question: How much would it cost to create a 'Quantum computer' and over the years, is it likely that we will all individually own one?

      It’s hard to guess how much they cost to build, but there is currently a company called D-Wave that currently sells a type of quantum computer. Their machine costs about $2 million to buy.

      As we get better and better at making quantum computers, I think it is quite possible that you and I will have them in our homes attached to our normal PC’s. This will probably not be for another 20 years or so though!
