Higher Rank Matricial Ranges and Hybrid Quantum Error Correction
David W. Kribs, Ningping Cao, Chi-Kwong Li +3
We introduce and initiate the study of a family of higher rank matricial ranges, taking motivation from hybrid classical and quantum error correction coding theory and its operator…
Approximate Quasiorthogonality of Operator Algebras and Relative Quantum Privacy
David W. Kribs, Jeremy Levick, Mike Nelson +2
We show that the approximate quasiorthogonality of two operator algebras is equivalent to the algebras being approximately private relative to their conditional expectation quantum…
Quantum Complementarity and Operator Structures
D. W. Kribs, J. Levick, M. I. Nelson +2
We establish operator structure identities for quantum channels and their error-correcting and private codes, emphasizing the complementarity relationship between the two perspecti…
Can chaos be observed in quantum gravity?
Bianca Dittrich, Philipp A. Hoehn, Tim A. Koslowski +1
Full general relativity is almost certainly 'chaotic'. We argue that this entails a notion of nonintegrability: a generic general relativistic model, at least when coupled to cosmo…
Chaos, Dirac observables and constraint quantization
Bianca Dittrich, Philipp A. Hoehn, Tim A. Koslowski +1
There is good evidence that full general relativity is non-integrable or even chaotic. We point out the severe repercussions: differentiable Dirac observables and a reduced phase s…
