Entanglement beyond subsystems
Lorenza Viola, Howard Barnum, Emanuel Knill +2
We present a notion of generalized entanglement which goes beyond the conventional definition based on quantum subsystems. This is accomplished by directly defining entanglement as…
Entanglement as an Observer-Dependent Concept: An Application to Quantum Phase Transitions
Gerardo Ortiz, Rolando Somma, Howard Barnum +2
This paper addresses the following main question: Do we have a theoretical understanding of entanglement applicable to a full variety of physical settings? It is clear that not onl…
Introduction to NMR Quantum Information Processing
R. Laflamme, E. Knill, D. G. Cory +11
After a general introduction to nuclear magnetic resonance (NMR), we give the basics of implementing quantum algorithms. We describe how qubits are realized and controlled with RF…
Introduction to Quantum Information Processing
E. Knill, R. Laflamme, H. Barnum +7
As a result of the capabilities of quantum information, the science of quantum information processing is now a prospering, interdisciplinary field focused on better understanding t…
Introduction to Quantum Error Correction
E. Knill, R. Laflamme, A. Ashikhmin +3
In this introduction we motivate and explain the ``decoding'' and ``subsystems'' view of quantum error correction. We explain how quantum noise in QIP can be described and classifi…
NMR Quantum Information Processing and Entanglement
Raymond Laflamme, David G. Cory, Camille Negrevergne +1
In this essay we discuss the issue of quantum information and recent nuclear magnetic resonance (NMR) experiments. We explain why these experiments should be regarded as quantum in…
