Figure 4
Simulation of the particle stationary state (\(n=3\)) in the well. The X0 curve is the initial state of the particle (for t = 0 s). Other curves are result of simulation for time \(t=4.5\cdot 10^{-16}\) s. The XS curve is result of the QDST simulation while the XF curve is result of simulation based on the QFT algorithm. The right plot shows the momentum representation of the particle state (for the QFT method only positive values of momentum are shown)
