A brief introduction to operator quantum error correction
David W. Kribs
We give a short introduction to operator quantum error correction. This is a new protocol for error correction in quantum computing that has brought the fundamental methods under a…
A unified framework for graph algebras and quantum causal histories
David W. Kribs
We present a mathematical framework that unifies the quantum causal history formalism from theoretical high energy physics and the directed graph operator framework from the theory…
Isometric dilations of non-commuting finite rank -tuples
Kenneth R. Davidson, David W. Kribs, Miron E. Shpigel
A contractive -tuple has a minimal joint isometric dilation where the 's are isometries with pairwise orthogonal ranges. This determines…
Inductive limit algebras from periodic weighted shifts on Fock space
David W. Kribs
Non-commutative multivariable versions of weighted shift operators arise naturally as `weighted' left creation operators acting on the Fock space Hilbert space. We identify a natur…
The C*-envelope of the tensor algebra of a directed graph
Elias Katsoulis, David Kribs
Given an arbitrary countable directed graph we prove the C*-envelope of the tensor algebra coincides with the universal Cuntz-Krieger algebra associated with . Our…
The algebras of higher rank graphs
David W. Kribs, Stephen C. Power
We begin the study of a new class of operator algebras that arise from higher rank graphs. Every higher rank graph generates a Fock space Hilbert space and creation operators which…
