I How are quantum bits implememted?

  1. Dec 13, 2016 #1
    Its very easy to pull a logic gate or transistor circuit of the internet for example and begin to understand how it represents physical bits, by either having 5V across the circuit or below 3.3V. But I was wondering what are some of the methods for representing qubits from a hardware perspective.

    I have already looked on Wikipedia and find the explanation to be very abstract and vague.

    This wiki article has a table of implementations halfway into the article:


    see the Physical Representation section.

    Here's a discussion of the IBM quantum computing web interface:


    I couldn't find a pictorial article on the various qubit systems though.

    I found this powerpoint discussion which talks about one such system and superposition:
