Fig. 3: Fidelities of the single-qubit gates.
From: Realising and compressing quantum circuits with quantum reservoir computing
We show the fidelity distributions for different single-qubit gates over 2000 uniformly at random generated states. a–f show the fidelity distributions for Pauli-X, Y, Z, Hadamard, phase and π/8 gates, respectively. For these gates a single network node is sufficient. A larger quantum network with 6 sites can also be considered, see Supplementary Section 2. The average fidelities for all the single qubit gates are larger than 0.9984. Here, we use P/E0 = (60, 60, 0.1, 4.96, 0.1, 0.1) and τE0/ℏ = (3.08, 16.68, 6.28, 1.53, 3.07, 4.71) for (a to f), respectively, and 10 randomly generated pure states for training. E0, P and τ are energy, driving strength and evolution time, respectively.
