Table 1 Parameters obtained after fitting the measured fidelities of systems prepared in states \(|{\Psi _{1}}\rangle =(|{01}\rangle +|{10}\rangle )/\sqrt{2}\), \(|{\Psi _{2}}\rangle =(|{001}\rangle +|{010}\rangle +|{100}\rangle +|{111}\rangle )/2\) and \(|{\Psi _{3}}\rangle =(|{001}\rangle +|{010}\rangle +|{100}\rangle +|{111}\rangle )/2\) after application of \(N\in [1,600]\) LEOs to the linear function in Eq. (11).
