# Validation and administration of a conceptual survey on the formalism and postulates of quantum mechanics

@article{Marshman2019ValidationAA, title={Validation and administration of a conceptual survey on the formalism and postulates of quantum mechanics}, author={Emily Megan Marshman and Chandralekha Singh}, journal={Physical Review Physics Education Research}, year={2019} }

We developed and validated a conceptual survey that focuses on the formalism and postulates of quantum mechanics covered in upper-level undergraduate quantum mechanics courses. The concepts included in the Quantum Mechanics Formalism and Postulate Survey (QMFPS) focus on Dirac notation, the Hilbert space, state vectors, physical observables and their corresponding Hermitian operators, compatible and incompatible observables, quantum measurement, time-dependence of quantum states and expectation…
