Figure 9From: Multi-qubit joint measurements in circuit QED: stochastic master equation analysis State fidelity \(\pmb{F_{\pm} = \sqrt{ \langle \psi _{\pm} \vert \rho \vert \psi_{\pm} \rangle } }\) for the gate-based measurement acting on the initial state \(\pmb{\vert {+}{+}{+} \rangle}\) . Inset: small p regime, in which \(F_{\pm} \sim1 - 4p\).Back to article page
