Quantum computing has existed as a theoretical concept for some time. I recently saw some talks on quantum computing and I’ve been inspired to start researching the field myself. There are now a handful of (known) quantum computers in existence, some of which, such as the “IBM Q Experience” allow you to execute real quantum programs. I’ll give an overview of the state of the art, what the potential of quantum computing is, what its limitations might be and a small dose of speculation on what applications could be suited to to quantum computers and when they might start to be really useful.

I’ve also designed a demonstration of Quantum Computing, using Microsoft’s Q# (not a real quantum computer, it is a simulator designed to run on a traditional digital computer) called “Clementine’s Cat”. I was inspired to make Clementine’s Cat when I described Shrodinger’s Cat to my daughter and she was horified that anybody would do such a thing to their cat. So Clementine’s Cat is a humane modern spin on the traditional quantum thought experiment in which no cats are harmed, either theoretically or in reality.
