I am just being annoyingly pedantic, but I do not think a Clifford circuit (both of your examples fall in this category) is a good quantum hello world, because they are trivial to simulate efficiently on a classical computer. But I do not have better suggestions.
- chunky1994 5y agoI don't think a "hello world" type of program/circuitry(?) needs to be unique to a quantum computer. It just needs to be expressible with a quantum circuit. Similar to how you can have hello world in both ruby and python, but arrive at them with different syntax and compilers.
- josefx 5y agoIsn't that the case for literally anything you could run on the current state of the art quantum computers? The troll answer of simulating a qbit using a qbit excluded.
- Bjartr 5y agoAnd displaying "Hello World" can be done trivially with a pencil and paper. That doesn't make doing so in a classical programming language devoid of value.
- krastanov 5y agoSure, but there is value in a "Hello World" being focused on what is special about the hardware/language. Look at Haskell and OCaml tutorials for instance: they all explicitly say stuff like "let us start with the 'Hello World' of functional languages, namely, implementing the Fibonacci (or factorial) function recursively".
