(a) Teleportation fidelity as a function of WM strength \((\omega )\) and WMR strength \((q)\) with decoherence in mode A or B. The gray plane is the teleportation fidelity without any protection (b) Protection success probability as a function of WM strength \((\omega )\) and WMR strength \((q)\) with decoherence in mode A or B. Here \(r=0.5\) and \(\theta =\frac{\pi}{2}\). The gray area is the corresponding protection success probability of no protection protocol
