	abstract = {The qubitdyne protocol allows for quadrature detection of bosonic modes in stationary systems via repeated weak interactions with an auxiliary qubit. This approach circumvents the loss of photons in the cavity. While the earlier implementation of qubitdyne protocol utilizes constant coupling, Strandberg, et al. [<em>PRL</em> <strong>133</strong>, 063601 (2024)], suggests time-dependent coupling can significantly enhance the measurement process. In this study, we quantitatively analyze the efficiency of the qubitdyne protocol with constant and linearly increasing time-dependent couplings. The simulations were carried out with Fock, cat, and coherent states with increasing values of photons in the cavity (α = 4, 6, 8). The accuracy of the reconstruction was quantified by calculating the Kolmogorov-Smirnov (KS) statistic with respect to the ideal homodyne distributions. The results reveal that the constant coupling results in large deviations and high KS values up to ≈0.9 for the reconstructed quadrature distributions attributed to inefficiency in depleting the cavity. However, the time-dependent coupling results in low KS values (< 0.1) for all the reconstructed distributions. This reduces measurements by up to six times.},

	abstract = {The scattering of a quantum particle in one dimension from a P{\"o}schl-Teller potential is demonstrated using a quantum simulator, Qiskit, consisting of 10 qubits. Solving the Schr{\"o}dinger equation with this potential is implemented as the action on the qubits by Fourier transforms and diagonal operators represented as controlled-phase shift gates. Hence, a quantum algorithm is constructed that is capable of modulating the reflection and transmission of a quantum particle by varying the shape of the P{\"o}schl-Teller potential using a single parameter λ. The results obtained from Qiskit are verified using symbolic architecture simulations.},
