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…
A quantum computing primer for operator theorists
David W. Kribs
This is an exposition of some of the aspects of quantum computation and quantum information that have connections with operator theory. After a brief introduction, we discuss quant…
Noiseless subsystems for collective rotation channels in quantum information theory
J. A. Holbrook, D. W. Kribs, R. Laflamme +1
Collective rotation channels are a fundamental class of channels in quantum computing and quantum information theory. The commutant of the noise operators for such a channel is a C…
