Abstract Title: Investigating student understanding of quantum entanglement
Abstract: Quantum entanglement is a central concept of quantum theory for multiple particles. Entanglement played an important role in the development of the foundations of the theory, and makes possible modern applications in quantum information technology including teleportation, quantum computing and cryptography.
We have investigated student understanding of two-particle quantum entanglement at the introductory and advanced undergraduate levels. We collected student activity responses using two versions of an interactive QuVis simulation "Entanglement: The nature of quantum correlations" (www.st-andrews.ac.uk/physics/quvis/simulations_html5/sims/entanglement/entanglement.html) and carried out a small number of student interviews.
Common incorrect ideas found in this work include stating that all entangled states must be maximally entangled (i.e. show perfect correlations or anticorrelations), that the spins of particles in a product state have definite values (are not in a superposition state with respect to spin) and difficulty factorizing product states. Outcomes from this work will inform further development of the QuVis Entanglement simulation.
