Entangled states and quantum gates are two of the fundamental building blocks for quantum information technologies. In this seminar, I will describe novel techniques for realizing these processes using dynamical states in a one-dimensional harmonic oscillator.

In order to efficiently study the dynamics of this system, we have developed a GPU -accelerated solver for the time-dependent Schrödinger equation which is up to x1000 faster than previous methods used within the group. Using these simulations, we will show that by tuning the interaction strength between coherent states oscillating in a harmonic potential, we can generate maximally entangled states. By studying the energy spectrum of the system, we have shown that this technique is robust against perturbations. Finally, I will describe how spin-orbit interaction can be introduced into the simulations and I will show how its effect on the entanglement processes we have proposed can be corrected for by choosing appropriate initial conditions.
