Performance versus fluctuations (N = 20). (a) The transmission fidelity F(tout) of spin chain. The transfer fidelity F(tout) of \({J}_{1}=\sqrt{19}\alpha \). (b–d) Blockade fidelity of spin chain with sinusoidal driving, triangular-well driving and square-well driving, respectively. The blockade fidelity BF(tout) for different values of amplitude(green line), frequency (red-dashed line) and J1, where Aj = 30.06α, Bj = 36.56α,Cj = 25α, ω = 25α, \({J}_{1}=\sqrt{19}\alpha \) and the ideal parameters are Aj = 30.06, Bj = 36.56, Cj = 25, ω = 25, \({J}_{1}=\sqrt{19}\). Here Aj, Bj, Cj, ω, J1 are amplitude, frequency and interaction coefficient between adjacent particles, respectively.
