| Apr 14, 2017 at 20:43 | comment | added | ZeroTheHero | The paper itself does not use the word "coexist"; in my mind "a qubit can a 0 and a 1 at the same time" is correct provided it is understood that the state of the qubit can produce two outcomes $0$ and $1$ that are mutually exclusive; this point is likely lost on the layperson: as pointed out by @gautampk the word "coexist" can be understood to convey the reverse, i.e. that the outcomes are anything but mutually exclusive... If you don't like "state", not sure your edit to use "eigenstates" is better... after all eigenstates are also states... | |

| Apr 14, 2017 at 20:24 | comment | added | Pietroid96 | I tried to use the terms as thinking on the side of the non-academic people and laymen. Coexist at the same time is very clear when taking into account that these people don't even know about vectors and Hilbert spaces, and all that they know are classical states and a simple idea of "quantum weirdness that makes stuff be two things at once". | |
| Apr 14, 2017 at 19:40 | comment | added | ACuriousMind♦ | This question really stands and falls with what you mean by "coexisting" here, and the question itself unfortunately gives little information about that. I'm unconvinced this is actually a physics issue and not just one where different people have different ideas of what states "coexisting" actually is supposed to mean. | |

Based on the discussions, I just rewrote states as "states". By these "states" I mean vectors that are eigenstates of an observable. In the classical sense, states like Heads and Tails, 0 and 1, etc.
