I am thinking as quantum computing is just a new word in tech, so let to explore it by building it or a prototype based on it so I am just wanted help in setting up and initial steps which should I keep in mind. Please tell me about each implementation step.

    $\begingroup$ While the basic answer is along the lines of "with a fair bit of investment and experience, you could technically build something with a couple of qubits", the actual answer is implementation dependent and even then, there are different ways to go about doing so for each implementation, so I suggest that you narrow this down by thinking about what implementation you'd want to know about (if you've got any specific questions about specific implementations, feel free to ask), then e.g. making an edit to ask about a specific experimental set-up would narrow this down considerably $\endgroup$ – Mithrandir24601 Jul 19 '18 at 21:31
  • $\begingroup$ can you give just an overview of these step ? $\endgroup$ – Vashi Jul 21 '18 at 8:24
  • $\begingroup$ Not really as things currently stand because it just depends on too much - the first thing is which implementation do you want to know about? $\endgroup$ – Mithrandir24601 Jul 21 '18 at 9:19
  • $\begingroup$ for all practical purposes, the answer is no (unless of course you happen to have on your hands a lot of money and people with the relevant expertise) $\endgroup$ – glS Jul 21 '18 at 16:33
  • $\begingroup$ @Mithrandir24601 you could technically build something with a couple of qubits". what can be buid and how should i start ? $\endgroup$ – Vashi Jul 21 '18 at 17:11
