Quantum Information Propagation Preserving Computational Electromagnetics
We propose a new methodology, called numerical canonical quantization, to
solve quantum Maxwell's equations useful for mathematical modeling of quantum
optics physics, and numerical experiments on arbitrary passive and lossless
quantum-optical systems. It is based on: (1) the macroscopic (phenomenological)
electromagnetic theory on quantum electrodynamics (QED), and (2) concepts
borrowed from computational electromagnetics. It was shown that canonical
quantization in inhomogeneous dielectric media required definite and proper
normal modes. Here, instead of ad-hoc analytic normal modes, we numerically
construct complete and time-reversible normal modes in the form of traveling
waves to diagonalize the Hamiltonian. Specifically, we directly solve the
Helmholtz wave equations for a general linear, reciprocal, isotropic,
non-dispersive, and inhomogeneous dielectric media by using either
finite-element or finite-difference methods. To convert a scattering problem
with infinite number of modes into one with a finite number of modes, we impose
Bloch-periodic boundary conditions. This will sparsely sample the normal modes
with numerical Bloch-Floquet-like normal modes. Subsequent procedure of
numerical canonical quantization is straightforward using linear algebra. We
provide relevant numerical recipes in detail and show an important numerical
example of indistinguishable two-photon interference in quantum beam splitters,
exhibiting Hong-Ou-Mandel effect, which is purely a quantum effect. Also, the
present methodology provides a way of numerically investigating existing or new
macroscopic QED theories. It will eventually allow quantum-optical numerical
experiments of high fidelity to replace many real experiments as in classical
electromagnetics.Comment: 17 pages, 11 figures, journal article submitted to Physical review A

The impact of clinical placements on the emotional intelligence of occupational therapy, physiotherapy, speech pathology, and business students: a longitudinal study
Background: Emotional intelligence (EI) is a critical skill for healthcare practitioners. Minimal longitudinal research has tracked the changes in EI of therapy students over their final full-time clinical placements.
Methods: The Emotional Quotient Inventory (EQ-i2.0) measured the EI of 283 therapy students and 93 business students (control group who do no clinical placements) at three time points over a 16-month period, the same period that the therapy students participated in clinical placements.
Results: Analysis of the therapy students showed significant increases over the 16 months of the study in Total EI score, as well as nine other EI skills. However, large percentages of students reported declining scores in emotional expression, assertiveness, self-expression, and stress tolerance, with some students reporting low EI scores before commencing full-time extended clinical placements.
Conclusions: The study contributes to new knowledge about the changing EI skills of therapy students as they complete their full-time, extended placements. Emotional intelligence in student therapists should be actively fostered during coursework, clinical placements and when first entering the workforce. University educators are encouraged to include EI content through the therapy curricula. Employers are encouraged to provide peer coaching, mentoring and workshops focused on EI skills to recent graduates
