| 21. | Non-clonability can be seen as a property of arbitrary sets of quantum states.
|
| 22. | Not surprisingly, this suffers from the same pitfalls as in quantum state tomography.
|
| 23. | This material can be of any excited " ) quantum states.
|
| 24. | You have millions of atoms condensed to the same quantum state.
|
| 25. | Adding particles or reducing the volume forces the particles into higher-energy quantum states.
|
| 26. | However, these operators literally create and annihilate particles with a given quantum state.
|
| 27. | :: A classical bit is consistent with many different quantum states.
|
| 28. | So, here is how quantum state and wave function are related.
|
| 29. | In other words, a quantum state can not be measured reliably.
|
| 30. | This property allows superpositions of quantum states to be solutions of the Schr�dinger equation.
