Recovery of polarization entanglement in partially coherent photonic qubits.

Partially coherent photonic qubits, owing to their robustness in propagation through random media compared to fully coherent qubits, find applications in free-space communication, quantum imaging, and quantum sensing. However, the reduction of spatial coherence degrades entanglement in qubits, adversely affecting entanglement-based applications. We report the recovery of entanglement in the partially coherent photonic qubits generated using a spontaneous parametric downconversion process despite retaining their multimode nature.

A heutagogical interactive tutorial involving Fishbowl with Fish Battle and Round Robin Brainstorming: A novel syndicate metacognitive learning strategy.

Background: The increasing tutorial size poses every teacher with the problem of student attention and participation; hence, newer strategies are needed to engage adult learners into cooperative learning. This study aims to assess the knowledge gained and retained and perceptions of students using an interactive syndicate learning style tutorial vis-a-vis conventional tutorials.

Methods: A quasi-experimental crossover study was conducted wherein students of phase 1 MBBS physiology tutorials were divided into two batches (interactive tutorials involving learning Fishbowl with Fish Battle and Round Robin Brainstorming and conventional didactic tutorials), with 65 students in each over 3 days.
