Fig. 2: Joint probabilities.
From: Experimental characterization of the energetics of quantum logic gates
Comparison between theoretical (lines) and experimental (dots) joint probabilities \(p({E}_{{1}_{A}{\phi }_{B}}^{{\rm{in}}},{E}_{{1}_{A}{\phi }_{B}}^{{\rm{fin}}})\) as a function of time t, with ωint/ωL = 5 in natural units, ρ0 as in Eq. (9) and \({\left|V\right\rangle }_{k}=(1,0)\), \({\left|H\right\rangle }_{k}=(0,1)\) for both qubits k = A and B. We show \(p({E}_{{1}_{A}{0}_{B}}^{{\rm{in}}},{E}_{{1}_{A}{0}_{B}}^{{\rm{fin}}})\) (blue dots and solid line), \(p({E}_{{1}_{A}{1}_{B}}^{{\rm{in}}},{E}_{{1}_{A}{0}_{B}}^{{\rm{fin}}})\) (red dots and dotted line), \(p({E}_{{1}_{A}{0}_{B}}^{{\rm{in}}},{E}_{{1}_{A}{1}_{B}}^{{\rm{fin}}})\) (black dots and dashed line), and \(p({E}_{{1}_{A}{1}_{B}}^{{\rm{in}}},{E}_{{1}_{A}{1}_{B}}^{{\rm{fin}}})\) (green dots and dot-dashed line).
