David Deutsch, British Literature and Classical Music: Cultural Contexts 1870–1945

On an Argument of David Deutsch

We analyse an argument of Deutsch, which purports to show that the deterministic part of classical quantum theory together with deterministic axioms of classical decision theory, together imply that a rational decision maker behaves as if the probabilistic part of quantum theory (Born’s law) is true. We uncover two missing assumptions in the argument, and show that the argument also works for a...

British Cultural Studies , Active Audiences and the Status of Cultural Theory An Interview with David Morley

British cultural studies, represented perhaps chiefly by the so-called Birmingham School, is much marked by its strong orientation towards the application of grounded theory in the analysis of concrete cases, rather than the development of abstract Theory with a Capital T (in Stuart Hall’s words). As a leading figure of the Birmingham School and a key representative of the active audience model...

Constructor theory of information David Deutsch 1 and

We propose a theory of information expressed solely in terms of which transformations of physical systems are possible and which are impossible— i.e. in constructor-theoretic terms. It includes conjectured, exact laws of physics expressing the regularities that allow information to be physically instantiated. Although these laws are directly about information, independently of the details of pa...

Interventions and Cultural Contexts

Efficient classical simulation of the Deutsch-Jozsa and Simon's algorithms

A long-standing aim of quantum information research is to understand what gives quantum computers their advantage. This requires separating problems that need genuinely quantum resources from those for which classical resources are enough. Two examples of quantum speed-up are the Deutsch–Jozsa and Simon’s problem, both efficiently solvable on a quantum Turing machine, and both believed to lack ...
