This series is a crash course introduction to a handful of advanced topics designed to tackle the general problem of how to engineer Positive Operator-Valued Measures (POVMs) using observable building blocks, the so-called Instrument Manifold Program.  This program emerged from a recent fundamental breakthrough: how to realize the measurement of a spin’s direction, a.k.a. the spin-coherent-state POVM, a spherical set of outcomes analogous to the well known coherent-state POVM of the standard phase plane. **Outline:** Oct 27: Introduction: The Planimeter and the ``Spherimeter'' Oct 30: Indirect Measurement and System-Meter Interaction Nov 03: POVMs and Decoherence Nov 06: Generalized Observables: Phase-Point and Spin-Direction Nov 10: Transformation Groups and Enveloping Algebras Nov 13: Frame Operators and Quasi-Probability Distributions Nov 17: The Arthurs-Kelly (1965) and D’Ariano (2002) Measurements Nov 20: Optical Homodyne and Heterodyne Nov 24: Continuous Measurement and the Kraus-Operator Density Nov 27: Simultaneous Measurements of Non-Commuting Observables Dec 01: Instrumental Groups and Universal Markov Processes Dec 04: Universal Instrument Navigation Dec 08: Non-Euclidean Geometry Dec 11: Non-Euclidean POVMs **Location & Building Access:** Alice Room, 3rd Floor, Perimeter Institute, 31 Caroline St N, Waterloo (Exception - November 27 in Space Room, 4th Floor) **Registration:** Please sign-up here: https://forms.office.com/r/dEA4EUq0CU Participants who do not have an access card for Perimeter Institute must sign in at the security desk before each session.
