Table 1 We present some examples of the quantum states and corresponding quantum operations required for QAV-7
Number of voters | Quantum state | Operation \(O_{i}\) of voters \(V_{i}\) used for vetoing |
|---|---|---|
3 | Bell or GHZ state | \(O_{0}=X \), \(O_{1}=iY\), \(O_{2}=Z \) |
4 | GHZ state | \(O_{0}=X\otimes{I} \), \(O_{1}=iX\otimes X\), \(O_{2}=iY\otimes X \), \(O_{3}=iY\otimes{I}\) |
4 | 4-qubit cluster state | \(O_{0}=X\otimes iY \), \(O_{1}=X\otimes Z \), \(O_{2}=iY\otimes Z \), \(,O_{3}=iY\otimes iY \) |
