# How to prepare state |+⟩? [closed]

Is there a method how to prepare quantum pure state $$|+⟩ = \frac{1}{\sqrt{2}}(|0⟩+|1⟩)$$ ? Thanks a lot for concrete answer.

• Sure there is, but the specifics depend on what quantum system do you use to encode the qubit. Is it the polarization of a photon? Is it a spin of electron? Is it something else? You need to be concrete yourself, if you want a concrete answer. – Adam Latosiński Mar 23 at 22:48
• Experimentally? What is the basis for the 0 and 1 states? – SuperCiocia Mar 23 at 23:05
• ... and it actually depends on the basis as well... – ZeroTheHero Mar 24 at 0:40
• On quantum computers based on gate model (e.g. IBM Q), it can be prepared by application of Hadamard gate on state $|0\rangle$. – Martin Vesely Mar 25 at 15:21
