Fig. 4: Controlling the tunneling amplitude by tuning the detuning.
a Probability of the transition \(\left|10\right\rangle \to \left|01\right\rangle\) between the qubits as a function of the ratio between the relative detuning Δs and the tunneling amplitude g between the nearest-neighbor sites. Here the transition occurred with a unitary evolution for a time duration τ. b A three site lattice system with nearest-neighbor tunneling amplitude g. c The site energies: the site at the middle has a relative energy Δs with respect to the qubit sites placed at the two ends. We consider g/α = 2.07, and a time duration τ = 1.08\({\hbar}\)/α.
