Performance loss of the system at level \(l+1\) for different failure behaviors at level \(l\), different combinations of \(P(|\Psi _{\alpha _{j},i}^{l+1}\rangle =|1\rangle \vert |\Psi _{\alpha ^{*}_{j},i}^{l+1},\Psi _{\alpha _{j},i-1}^{l+1}\rangle =|ab\rangle )\), where \(|ab\rangle \in \{|11\rangle ,|00\rangle \}\), and \(P(|\Psi _{\alpha _{j},i}^{l+1}\rangle =|1\rangle \vert |\Psi _{\alpha ^{*}_{j},i}^{l+1},\Psi _{\alpha _{j},i-1}^{l+1}\rangle =|10\rangle )=P(|\Psi _{\alpha _{j},i}^{l+1}\rangle =|1\rangle \vert |\Psi _{\alpha ^{*}_{j},i}^{l+1},\Psi _{\alpha _{j},i-1}^{l+1}\rangle =|01\rangle )=0.5\). First approach. Three qubits case.
