Witness Algebra and Anyon Braiding
Andreas Blass, Yuri Gurevich
Topological quantum computation employs two-dimensional quasiparticles called anyons. The generally accepted mathematical basis for the theory of anyons is the framework of modular…
Negative probabilities, II: What they are and what they are for
Andreas Blass, Yuri Gurevich
A signed probability distribution may extend a given traditional probability from observable events to all events. We formalize and illustrate this approach. We also illustrate its…
Braided distributivity
Andreas Blass, Yuri Gurevich
In category-theoretic models for the anyon systems proposed for topological quantum computing, the essential ingredients are two monoidal structures, and . The fo…
Who needs category theory?
Andreas Blass, Yuri Gurevich
In mathematical applications, category theory remains a contentious issue, with enthusiastic fans and a skeptical majority. In a muted form this split applies to the authors of thi…
Common Denominator for Value and Expectation No-go Theorems: Extended Abstract
Andreas Blass, Yuri Gurevich
Hidden-variable (HV) theories allege that a quantum state describes an ensemble of systems distinguished by the values of hidden variables. No-go theorems assert that HV theories c…
