After a quick review of the basic theory of quantum optomechanical systems, based largely on linearized Heisenberg–Langevin equations, this chapter focuses on selected topics related to quantum measurement and quantum optomechanics. Included are: a comprehensive discussion of the quantum limit on the added noise of a continuous position detector, following the quantum linear response approach; a detailed discussion of the role of noise correlations, and how these can be achieved in an optomechanical cavity (by using squeezed input light, or by modifying the choice of measured output quadrature); and a discussion of back-action evading measurements of a mechanical quadrature, discussing how this can be achieved in a two-tone driven cavity system. The chapter ends with a quick introduction to the theory of conditional continuous quantum measurement, and a discussion on how a back-action evading measurement can be used to produce conditional mechanical squeezed states.

The Relationship

This article seeks to explore the quantum notion that to ‘see’ an entanglement is to break it in the context of an ‘experiment’ regarding the ongoing impact of traumatic political memory on the present. The analysis is a product of collaboration over the past four years between the two authors, one a scholar of international relations, the other a therapeutic practitioner with training in medical physics. Our focus is the conceptual claim that ‘seeing’ breaks an entanglement rather than the experiment itself. The first section explores a broad contrast between classical and quantum measurement, asking what this might mean at the macroscopic level. The second section categorizes Wendt’s claim about language as a form of expressive measurement and explores the relationship to discourse analysis. The third section explores the broad contours of our experiment and the role of a somewhat different form of non-linear expressive measurement. In the final section, we elaborate the relationship between redemptive measurement and breaking an entanglement, which involves a form of ‘seeing’ that witnesses to unacknowledged past trauma.

AbstractWhitehouse adapts insights from evolutionary anthropology to interpret extreme self-sacrifice through the concept of identity fusion. The model neglects the role of normative systems in shaping behaviors, especially in relation to violent extremism. In peaceful groups, increasing fusion will actually decrease extremism. Groups collectively appraise threats and opportunities, actively debate action options, and rarely choose violence toward self or others.

AbstractIntuitions guide decision-making, and looking to the evolutionary history of humans illuminates why some behavioral responses are more intuitive than others. Yet a place remains for cognitive processes to second-guess intuitive responses – that is, to be reflective – and individual differences abound in automatic, intuitive processing as well.
