Researching for better instructional methods using AB experiments in MOOCs: results and challenges.

We conducted two AB experiments (treatment vs. control) in a massive open online course. The first experiment evaluates deliberate practice activities (DPAs) for developing problem solving expertise as measured by traditional physics problems.

Parallel state transfer and efficient quantum routing on quantum networks.

We study the routing of quantum information in parallel on multidimensional networks of tunable qubits and oscillators. These theoretical models are inspired by recent experiments in superconducting circuits. We show that perfect parallel state transfer is possible for certain networks of harmonic oscillator modes.

Entanglement and composite bosons.

We build upon work by C. K. Law [Phys.
