PIRSA:12040100  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
Depicting Non-locality
Speaker(s): Bob Coecke
Abstract: We establish a tight relationship between two key quantum theoretical notions: non-locality and complementarity. In particular, we establish a direct connection between Mermin-type non-locality scenarios, which we generalise to an arbitrary number of parties, using systems of arbitrary dimension, an... read more

The logic of quantum mechanics - take II
Speaker(s): Bob Coecke
Abstract: It is now exactly 75 years ago that John von Neumann denounced his own Hilbert space formalism: ``I would like to make a confession which may seem immoral: I do not believe absolutely in Hilbert space no more.'' (sic) [1] His reason was that Hilbert space does not elucidate in any direct manner the ... read more

CauCats: the backbone of a quantum relativistic universe of interacting processes
Speaker(s): Bob Coecke
Abstract: Our starting point is a particular `canvas' aimed to `draw' theories of physics, which has symmetric monoidal categories as its mathematical backbone. With very little structural effort (i.e. in very abstract terms) and in a very short time this categorical quantum mechanics research program has rep... read more

PIRSA:10030114  ( MP4 Medium Res , MP3 , PDF ) Which Format?
The compositional structure of multipartite quantum entanglement
Speaker(s): Bob Coecke
Abstract: Multipartite quantum states constitute a (if not the) key resource for quantum computations and protocols. However obtaining a generic, structural understanding of entanglement in N-qubit systems is still largely an open problem. Here we show that multipartite quantum entanglement admits a compositi... read more

PIRSA:09080013  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Interaction axiomatics for quantum phenomena.
Speaker(s): Bob Coecke
Abstract: In our approach, rather than aiming to recover the 'Hilbert space model' which underpins the orthodox quantum mechanical formalism, we start from a general `pre-operational' framework, and verify how much additional structure we need to be able to describe a range of quantum phenomena. This also ena... read more

Complementarity as a resource
Speaker(s): Bob Coecke
Abstract: TBA

PIRSA:09050010  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Quantum foundations minus probability theory
Speaker(s): Bob Coecke
Abstract: Researchers in quantum foundations claim (D'Ariano, Fuchs, ...): Quantum = probability theory + x and hence: x = Quantum - probability theory Guided by the metaphorical analogy: probability theory / x = flesh / bones we introduce a notion of quantum measurement within x, wh... read more

Where quantum meets logic, . . . in a world of pictures!
Speaker(s): Bob Coecke
Abstract: Yes, that's indeed where it happens. These pictures are not ordinary pictures but come with category-theoretic algebraic semantics, support automated reasoning and design of protocols, and match perfectly the developments in important areas of mathematics such as representation theory, proof theory,... read more
