Designing Stochastic Channels
Matthew A. Graydon, Joshua Skanes-Norman, Joel J. Wallman
Stochastic channels are ubiquitous in the field of quantum information because they are simple and easy to analyze. In particular, Pauli channels and depolarizing channels are wide…
Clifford groups are not always 2-designs
Matthew A. Graydon, Joshua Skanes-Norman, Joel J. Wallman
The Clifford group is the quotient of the normalizer of the Weyl-Heisenberg group in dimension by its centre. We prove that when is not prime the Clifford group is not a gr…
Conical Designs and Categorical Jordan Algebraic Post-Quantum Theories
Matthew A. Graydon
Physical theories can be characterized in terms of their state spaces and their evolutive equations. The kinematical structure and the dynamical structure of finite dimensional qua…
